EDITOR'S PEEFACE.

THE " Art of Prolonging Life," by Christopher William
Hufeland, a philosophic physician and professor of medicine
in the University of Jena, is a work enjoying a deserved
popularity in Germany ,'where it has gone through several
editions. Though translated into English, in 1797, it is
but little known in this country, less indeed, as it appeared
to the Editor, than its merits deserve ; and it is under the
hope of being able to fill a vacant niche in popular litera-
ture, and restoring to his proper sphere of usefulness an able
and accomplished instructor, that the Editor has now un-
dertaken the present edition of his book. In its English
costume, and bearing a dedication to George Christopher
Lichtenberg, Counsellor of State to his Britannic Majesty,
and one of the Professors in the University of Gbttingen,
the work was published in two octavo volumes, with respect-
able and roomy type, short lines, shorter pages, and broad
margins, an effectual prohibition to its wide diffusion. The
translation bears the impress of a master's hand ; it is ele-
gant and exact, and in the Editor's judgment, is the pro-
duction of the learned author's own pen. Under this belief,
the Editor has selected the translation of 1794, with its pure
and classic language, for the present volume, in preference
to a new translation from a later German edition.

The Reader will probably be struck, as was the Editor,

vi EDITOR'S PREFACE.

with the little real progress which has been made in the
science of living during the more than half a century since
the original work was first written ; and the feeling of a ne-
cessity for bringing the matter up to the present line of
march will be dissipated by its perusal. Indeed it seemed
to the Editor more fitting as a ground of wholesome reflec-
tion, that we should have placed before our eyes the philos-
ophy of half a century back, that we might thereby learn
how much still remained to be done, before our knowledge
of the subject could be regarded as complete.

With an elegant translation, then, done to his hand, all
that remained to the Editor was a labor of taste ; to adapt
the work to the modes of thinking and feeling of the present
day, certain truths, too true to be allowed to stand forth in
all their naked proportions, required a veil to be thrown
around the.m ; words that betrayed the foreign source of
the translation, and bore a meaning different to that which
would have been deduced from their construction, required
to be exchanged for terms of more obvious nationality ; and,
in a few instances, certain elaborate disquisitions, bordering
on absolute prose, needed to be expunged altogether. The
temple of knowledge, at the present day, is called on to put
forth all its allurements to invite mankind to enter its portals,
while with equal care its harsher features must be thrown
into the shade. The art of the arrangement consists in
softening the rude by its combination with the refined ; in
accustoming the senses to the subdued tints before the more
sombre shadows are developed. In this, and a few necessary
notes, the whole of the Editor's labor is embraced.

PREFACE.

THE life of man, physically considered, is a peculiar chem-
ico-animal operation ; a phenomenon effected by a concur-
rence of the united powers of Nature with matter in a con-
tinual state of change. This, like every other physical ope-
ration, must have its defined laws, boundaries, and duration,
so far as they depend on the sum of the given powers and
matter, their application, and many other external as well
as internal circumstances ; but, like every other physical
operation, it can be promoted or impeded, accelerated or re-
tarded. By laying down just principles respecting its essence
and wants, and by attending to observations made from
experience, the circumstances under which this process may
be hastened and shortened, or retarded and prolonged, can
be discovered. Upon this may be founded dietetic rules and a
medical mode of treatment for preserving life ; and hence
arises a particular science, the MACROBIOTIC, or the art of
prolonging it, which forms the subject of the present work.

This art, however, must not be confounded with the com-
mon art of medicine or medical regimen : its object, means,
and boundaries are different. The object of the medical art
is health; that of the macrobiotic, long life. The means
employed in the medical art are regulated according to the

Vlll PREFACE.

present state of the body and its variations ; those of the
macrobiotic, by general principles. In the first it is suffi-
cient if one is able to restore that health which has been
lost; but no person thinks of inquiring whether, by the
means used for that purpose, life, upon the whole, will be
lengthened or shortened ; and the latter is often the case in
many methods employed in medicine. The medical art must
consider every disease as an evil which cannot be too soon
expelled ; the macrobiotic, on the other hand, shows that
many diseases may be the means of prolonging life. The
medical art endeavors, by corroborative and other remedies,
to elevate mankind to the highest degree of strength and
physical perfection ; while the macrobiotic proves that here
even there is a maximum, and that strengthening, carried
too far, may tend to accelerate life, and consequently, to
shorten its duration. The practical part of medicine, there-
fore, in regard to the macrobiotic art, is to be considered
only as an auxiliary science which teaches us how to know
diseases, the enemies of life, and how to prevent and expel
them ; but which, however, must itself be subordinate to the
higher laws of the latter.

Long life has at all times been the chief wish, the principal
object of mankind ; but how confused and contradictory are
all the plans ever proposed for obtaining it! The stern
theologist derides such attempts ; and asks, if the period of
existence is not determined to every being and who is
able to add a hair-breadth to his stature, or a minute to the
duration of his existence ? The practical physician exclaims,
why do you search for the particular means of prolonging

life ? Employ my art ; take care of your health, guard
against diseases, and cure those which have appeared. This
is the only way to promote longevity. The adept shows his
vital elixir, and boldly asserts that those who will persevere
to take that incorporated spirit of life may hope to become
old. The philosopher endeavors to resolve the problem, by
teaching men to despise death, and to double life by enjoy-
ment. The innumerable legion of quacks and empirics, on
the other hand, who have gained the confidence of the mul-
titude, inspire them with a belief that there are no surer
means of becoming old, than to let blood at proper times, and
to use cupping, purgatives, etc.

It appeared to me, therefore, useful and necessary to
rectify the ideas of the public on a matter of so much impor-
tance ; and to bring this science back to solid and simple
principles, by which it might acquire that connection and
systematic order of which it hath hitherto been destitute.

For eight years this subject has been the favorite employ-
ment of my leisure hours ; and it will give me great happi-
ness if it be to others only half as serviceable as it has been
to me. The present melancholy age, so destructive to man-
kind, induced me to engage in this undertaking ; and the
idea of its being useful, while it afforded me the highest con-
solation, encouraged me to pursue my researches.

My chief aim was to establish the Art of prolonging Life
on systematic grounds, and to make known the means for
accomplishing that object ; but, to convey a proper idea of
the whole, it was necessary to comprehend some concomitant
circumstances which gradually presented themselves to my

X PREFACE.

notice. This, in the first place, appeared to be the best way
of giving a higher interest and more general value to many
dietetic rules ; because I have always found that much less
impression is made when one says, this or that substance, this
or that mode of living, is healthful or unhealthful, (since this
is relative, and depends on the strength or weakness of the
constitution as well as on other points, and has a reference
to the immediate consequences, which are often impercep-
tible, and therefore make those who are not physicians dis-
believe the whole,) than when the proposition is thus ex-
pressed these things, these modes of living, prolong or
shorten life; for this depends less on circumstances, and
cannot be judged of from the immediate consequences. And,
secondly, this work insensibly became a repository to which
I committed many of my favorite ideas ; where I indulged
in many digressions suited to a citizen of the world, and was
happy to have it in my power to connect these ideas by a
thread so beautiful and so extensive in joining every thing
as the thread of life.

According to the point of view under which I necessarily
considered my subject, it was natural that I should treat it,
not only medically, but also morally ; for, how is it possible
to write on human life, without taking into consideration its
connection with the moral world, to which it so peculiarly
belongs ? On the contrary, I have found more than once,
in the course of my labor, that the physical man cannot be
separated from his higher moral object : and I may, per-
haps, reckon it a small merit in the present performance,
that it will not only establish the truth and heighten the

PREFACE. Xi

value of the moral laws, in the eyes of many, by showing
that they are indispensably necessary for the physical sup-
port and prolongation of life but that it demonstrates, that
the physical nature of man has been suited to his higher
moral destination ; that this makes an essential difference be-
tween the nature of man and the nature of animals ; that with-
out moral cultivation man is in continual contradiction with
his own nature ; and that, by culture alone, he becomes even
physically perfect. May I be so fortunate, by these means,
as to accomplish two objects : not only to render the life of
man more healthful and longer; but also, by exciting his
exertions for that purpose, to make him better and more
virtuous ! I can at any rate assert, that man will in vain
seek for the one without the other, and that physical and
moral health are as nearly related as the body and the soul.
They flow from the same sources ; become blended together ;
and when united, the result is, HUMAN NATURE ENNOBLED

AND RAISED TO PERFECTION.

I must here observe, that as this work is not designed
merely for physicians, but for the public in general, I was
obliged in some points to be more diffuse, and in others
shorter, than if I had written for the former alone. I had,
in particular, a regard to young people ; because I am con-
vinced that the grounds of a long or a short life can be most
effectually laid at an early period ; and that, through unpar-
donable negligence in the education of youth, information on
this subject, so important to their physical happiness, is
entirely forgotten. I have, therefore, placed in the clearest
light those points most necessary to be known at an early

Xll PREFACE.

age ; and, in general, have treated my subject so that the
book may be put into the hands of young persons without
any danger : and it will afford me inexpressible joy if it
be not only recommended to them, but employed also in
schools, to convey instruction respecting their physical well-
being which must indeed be given in such seminaries, as
I unfortunately know, by long experience, that in colleges
it will be for the most part too late.

My readers, I hope, will forgive me for not supporting
with quotations every instance I have adduced, and every
fact related. My motive for omitting them was an appre-
hension of swelling the work too much, and of rendering it
too expensive. I must, however, remark, that the instances
given of the age of man are taken chiefly from Bacon's His-

TORIA VlT^E ET MORTIS.

To conclude, I will readily allow, that many parts of this
work might have been written in a better and fuller manner;
but I console myself with the agreeable persuasion, which no
one can deprive me of, that what I have said may be use-
ful, and that its utility will recommend it, and procure it
support.

THAT incomprehensible power, that immediate influ-
ence of the Deity which we call the vital principle,
pervades all nature. We everywhere behold phenom-
ena and effects which evidently announce its presence,
though under an infinite variety of modifications and
forms ; and the existence of life is proclaimed by the
whole universe around us. Life is that by which plants
vegetate, by which animals feel and are actuated ; but
in the highest degree of perfection, sensation, and form,
it appears, in man, the supreme link of the visible crea-
tion. If we survey the whole chain of being, we shall
nowhere find so complete a combination of almost all
the vivifying powers of nature ; nowhere so much vital

energy, united with so long duration as here. It needs
excite no surprise, therefore, that the most perfect pos-
sessor of this benefit should value it so highly ; and
that the bare idea of living and existing should be
attended with so much pleasure. All bodies become
the more interesting to us, the more we can ascribe to
them a kind of life and vital sensation. Nothing can
engage our attention so much; nothing induce us to
make so great sacrifices, and to call forth the most
extraordinary display and exertion of our most secret
powers, as the desire of preserving life, and of saving
it in the moment of danger. To those, even, -who are
deprived of its comforts and enjoyments ; to those who
suffer under the pain of incurable disease, or who be-
wail the loss of freedom in the gloom of a dungeon, the
idea of living and existing presents some charms ; and
it certainly requires a derangement of the finest organs
of sensation, a circumstance possible only in man ; a
total darkening and deadening of the mental faculties,
to render life to us either disgusting or indifferent. In
so wise and intimate a manner is the love of life, that
desire so worthy of a thinking being, that grand pillar
of individual and public felicity interwoven with our
frame. It was very natural for men, therefore, to con-
ceive the idea whether it might not be possible to pro-
long our existence, and to give more extent to the too
fleeting enjoyment of so valuable a blessing. This
question, indeed, has, at all times, engaged the atten-
tion of mankind, and in different ways. It has been a
favorite object of the deepest thinking minds ; it has
afforded a fine field for visionaries ; and has been the
principal allurement employed by quacks and impos-

tors : for we shall find that intercourse with spirits, the
secret of making gold, or the art of prolonging life,
were the pretences by which they deluded the multi-
tude, and imposed on the credulity of the public. It is
interesting, and may contribute something towards the
history of the human mind, to see by what various, and
often contrary, means people hoped to obtain that
benefit ; and, as in latter times, a Cagliostro and a Mes-
mer have supplied considerable materials for this sub-
ject, I hope I shall be forgiven if 'I here take a short
view, before I proceed to my main purpose, of the
principal methods that have been employed to lengthen
the duration of life.

An idea of this kind prevailed, even in the earliest
ages, among the Egyptians, the Greeks, and the Ro-
mans. In Egypt, a country which gave birth to si
many romantic notions, means were devised for the
attainment of this object ; and it is not improbable that
such researches may have been occasioned by the un-
healthfulness of the climate, owing to its great heat, and
the inundations of the Nile. It was believed there,
that life could be prolonged by the continued use of
emetics and sudorifics. It was, therefore, a general
custom to take, at least, two emetics every month ; and
instead of saying, How do you find yourself? one asked
another, How do you perspire ? This passion among
the Greeks, under the influence of a pure and serene
atmosphere, assumed a different direction. These peo-
ple were persuaded that a rational enjoyment of nature,
and the continual exercise of their powers, were the
surest means of strengthening the vital principle, arid of

prolonging life. Hippocrates, and all the physicians
and philosophers of that period, knew no other method
of accomplishing this end than by moderation ; the use
of free and pure air ; bathing ; and, above all, by daily
friction of the body and exercise. Particular directions
and rules were laid down for giving violent and gentle
motion to the body in a variety of ways : a particular
art, called the Gymnastic, hence arose ; and the great-
est philosophers and men of learning never forgot that
the body and the soul ought to be exercised in the
same proportion. This art, to us almost unknown, of
suiting exercise to the different constitutions, situations,
and wants of man ; of employing it, above all, as the
means of keeping his internal nature in proper activity,
and thereby not only rendering the causes of disease
ineffectual, but also curing diseases which have already
appeared, they, indeed, brought to an extraordinary
degree of perfection. One Herodicus, we are told,
carried these ideas so far that he compelled his patients
to walk ; to suffer their bodies to be rubbed ; and, the
more the disease weakened them, to endeavor to over-
come that weakness by strengthening the muscular
powers : and he had the good fortune to lengthen seve-
ral years, by this method, the lives of so many enfeebled
patients, that Plato reproached him with having acted
very unjustly towards these unfortunate people, in pro-
longing, by artificial means, that existence of which they
would always have less and less enjoyment. The clear-
est ideas and most agreeable to nature on preserving and
lengthening life may be found in Plutarch, who, by the
happiest old age, confirmed the truth of his prescrip-

MEANS ADOPTED BY THE ANCIENTS. 5

tions. His information on this subject, he concludes
with the following rules, which may suit also the present
age : " Keep your head cool, and your feet warm ; in-
stead of employing medicine for every indisposition,
rather fast a day ; and while you attend to the body,
never neglect the mind."

A singular method of prolonging life, ascribed also to
the earliest ages, was the Gerocomic ; or the custom of
inspiring new strength and vigor into a body enfeebled
under a load of years, by exposing it to the effluvia of
fresh and blooming youth. A well-known instance of
this practice may be found in the history of King David ;
and we learn from several passages in the writings of
the ancient physicians, that it was formerly much used,
and considered as of great efficacy in relieving the in-
firmities of age. Even in modern times this prescription
has been followed with advantage. The great Boer-
haave caused an old burgomaster of Amsterdam to sleep
between'two young persons ; and he assures us that the old
man acquired by these means a visible increase of vigor
and activity. When one, indeed, reflects what change
may be produced on diseased limbs by the vital evapo-
ration of animals newly killed, and what may be the
consequence of applying living animals to parts affected
with pain, this method will appear not to be altogether
despicable.

It is highly probable that the great value which the
Greeks and the Romans set upon inspiring pure sound
breath may have been founded on these ideas ; and the
following ancient inscription, discovered at Rome in the
last century, seems to allude to this subject :

ART OF PROLONGING LIFE.

JEsculapio et Sanitati.

L. Clodius Hermippus,
Qui vixit annos cxv. dies v.

Puellarum anhelitu.
Quod etiam post mortem ejus
Non parum mirantur physici,
Jam poster!, sic vitam ducite.

To ^Esculapius and Health

Dedicated

By L. Clodius Hermippus,
Who lived cxv years v days
By the breath of young maids.

Whether this inscription be authentic or not, it gave
occasion, in the beginning of the present century, to a
work in which one Dr. Cohausen endeavors, with much
learning, to prove that Hermippus was the master of a
training school, or teacher of female children, at Rome,
who, by living continually amidst a circle of young maids,
had been enabled to prolong his life to so great an age.
He advises people, therefore, with much benevolence, to
expose themselves, every evening and morning, to the
breath of young innocent maidens ; and asserts, that they
will thereby contribute in an incredible degree, to the
strengthening and preserving the vital power ; as, accord-
ing to the saying of the adepts, the first matter is con-
tained purest in the breath of innocence.

But that long period of darkness during the middle
ages, when all clear and natural conceptions were ban-
ished by fanaticism and superstition ; when the specula-
tive indolence of the cloister gave rise to some chemical
and physical discoveries, which served rather to bewil-
der than enlighten the understanding, and tended more
to promote credulity than enlarge knowledge, was the

most fertile in romantic notions on this subject. It was
during this night of ignorance that the most monstrous
chimeras of the human mind were produced ; and that
those absurd ideas of witchcraft, sympathy, the philoso-
pher's stone, occult qualities, chiromancy, cabala, uni-
versal remedies, were established, or at least propaga-
ted in the world ; and which unfortunately yet prevail,
and, though in a changed and modernized form, are
still employed to mislead mankind. Amidst that men-
tal darkness an opinion arose, that the preservation and
prolongation of life, which, as the gift of nature, had
been hitherto sought for by the most natural means,
could be obtained by chemical transmutations, by the
help of the first matter which men thought they had
caught in retorts, by guarding against the influence of
malignant constellations, and by other ridiculous con-
ceits of the like kind. I hope I shall, therefore, be
here permitted to mention a few of the plans then pro-
posed to mankind, which, notwithstanding their absurd-
ity, were nevertheless credited.

One of the most impudent quacks and greatest boast-
ers among the prolongers of life was Theophrastus Par-
acelsus, or, as he is better characterized by his whole
name, Philippus Aureolus Theophrastus Paracelsus
Bombastus ab Hohenheim. He had travelled over half
the world ; had collected receipts and wonder-working
medicines from all quarters and corners ; and, in partic-
ular, which was very uncommon, had studied in mines
the nature and management of metals. He began his
career by depreciating every thing before taught ; by
treating all the great public seminaries with the utmost
contempt ; by giving himself out as the first physician

8 ART OF PROLONGING LIFE.

and philosopher in the world ; and by solemnly assert-
ing that there was no disease which he could not cure,
no life which he could not prolong. As a proof of his
insolence and of the high tone in which the quacks of
the fifteenth century addressed the public, I shall here
quote the beginning of his principal work : " Ye must
give way to me, and not I to you ; ye must give way to
me, Avicenna, Rhases, Galen, Mesue; ye must give
way to me, ye of Paris, ye of Montpellier, ye of Swabia,
ye of Misnia, ye of Cologne, ye of Vienna, and what-
ever places lie on the Danube and the Rhine: ye
islands in the sea ; thou Italian, thou Dalmatian, thou
Athenian, thou Greek, thou Arabian, thou Israelite;
you must give way to me, and not I to you. The mon-
archy is mine ! " One may readily perceive that this au-
thor was not in the wrong when he said, " I am not fine-
spun by nature ; " but he had the art of clothing his ab-
surdities in so dark and mysterious language, that people
imagined they contained the deepest secrets which they
here and there sought to discover; and that, at any
rate, it was impossible to contradict him. By these
means, and by the new and accidental effects of some
chemical preparations which he first introduced into
medicine, he attracted great notice ; and his fame was
so far extended, that pupils and patients flocked to him
from every part of Europe ; and that even an Erasmus
did not disdain to consult him. He died, however, in
the fiftieth year of his age, though he possessed the
stone of immortality ; and when this vegetable sulphur

But it was not enough that recourse should be had to

chemistry and the world of spirits in order to prolong
our days ; the stars also must be employed for that pur-
pose. It was at the above period commonly believed,
that the influence of the stars, which people could not
allow themselves to suppose idle, ruled over the lives
and fortunes of men ; that every planet or constellation
could give to the whole frame of the being born under
it, a certain disposition to good or evil ; and that, conse-
quently, it was necessary only for an astrologer to know
the hour and minute of a person's birth to discover his
temperament, capacity, and fate ; to foretell the diseases
to which he would be subject, the death he would die,
and even the last day of his existence. This opinion
prevailed not only among the ignorant multitude, but
among the greatest, the wisest, and the most judicious
people of the age ; and it is astonishing how long and how
firmly they relied on these ideas, though instances could
not be wanting of such predictions proving altogether
false. Bishops, dignified clergymen, celebrated philos-
ophers and physicians, gave themselves up to the cast-
ing of nativities ; and lectures were read in colleges on
that subject, as well as upon cabala and the art of divi-
nation by punctures and circles. As a proof of what I
have advanced, let me here be permitted to say a few
words respecting the celebrated Thurneiser, the most
brilliant phenomenon of this kind ; a man truly singu-
lar. He resided in the last century at the electoral
court of Berlin, and was physician in ordinary, chemist,
nativity-caster, almanac-maker, printer, and booksel-
ler, all in one person. His reputation in astrology was
so great, that scarcely was there a child born in any re-
spectable family in Germany, Poland, Hungary, Den-

mark, and even England, whose parents did not imme-
diately despatch a messenger to him with an exact ac-
count of the moment of its birth. Eight, ten, and twelve
such nativities came to him often at one time ; and he
was at last so oppressed with them, that he was obliged
to engage an assistant in his business. Several vol-
umes of such questions are still preserved in the library
at Berlin, among which there appear some letters from
Queen Elizabeth. Besides, he composed annually an
astrological calendar, in which was described not only
the nature of the year in general, but also the principal
events of it ; and the days on which they would take
place were distinguished by abbreviations or signs. He,
indeed, for the most part, did not give the explanation
of them till the year following; but we find -instances of
his having been prevailed upon by money and fair words
to explain them before. It is astonishing what the art
of indefinite prophetic diction and the favor of accident
can effect. This calendar supported itself above twenty
years ; had a rapid and extensive sale ; and, with other
quackeries, procured to the author an estate of 100,000
florins.

But in an art which prescribed such certain and un-
passable boundaries to the life of man, how was it pos-
sible to find the means of prolonging it ? This was
-done in the following simple manner : it was supposed
that, as every man lay under the influence of a certain
star, every other body, plants, animals, and even whole
districts and single houses had each its own star, by
which it was ruled ; and that, besides, there was an in-
timate connection and sympathy between the planets
.and the metals. As soon as it was known from what

constellation or planet a man's misfortune or sickness
proceeded, nothing more was necessary than that he
should use such food, drink, and place of residence as
were under the government of an opposite planet. This
produced a new regimen, but totally different from that
of the Greeks already mentioned. If a day occurred
which, on account of its unfavorable constellation, gave
reason to apprehend severe sickness or other evils,
people retired to a spot which lay under the disposition
of a friendly star, or they took such nourishment and
medicine as, under the protection of a beneficent star,
would annihilate the influence of the malignant one.*
On the same grounds people hoped for a prolongation of
life by talismans and amulets. Because the metals
were in intimate connection with the planets, to wear a
talisman of the proper metal, which had been melted,
cast, and stamped under certain constellations, was suf-
ficient to appropriate to oneself the whole power and
protection of the planets with which it was connected.
People had not only talismans which averted the dis-
eases of one planet, but talismans for all astral diseases ;

* About that period, Marsilius Ficinus, in his Treatise on the
Prolongation of Life, advised all prudent people to consult an
astrologer every seven years, in order that they should be ap-
prised of the dangers which might threaten them during the fol-
lowing seven ; and in particular to respect and to use properly
the means of the three holy kings, Gold, Frankincense, and
Myrrh. M. Pansa, in the year 1470, dedicated to the Council at
Leipsic, a book De propaganda vita ; Aureus libellus : in which he
strongly advised these gentlemen, above all things, to make
known their favorable and unfavorable aspects, and to be on their
guard every seven years, because Saturn, a hostile, malignant
planet, ruled at those periods.

12 ART OF PROLONGING LIFE.

and some even which, by a particular mixture of dif-
ferent metals, and the peculiar art employed in melting
them, acquired the wonderful power of destroying the
whole influence of an unlucky nativity ; of advancing
to offices of dignity, and of rendering the most essential
service in regard to commerce or marriage. Was Mars
imprinted on a talisman in the sign Scorpio, and had it
been cast under that constellation, it rendered the per-
son who wore it invincible and invulnerable ; and the
German soldiers were so prepossessed with this idea,
that, as a French writer informs us, after a defeat which
they sustained in France,, amulets were found hanging
from the necks of all the killed and prisoners. The
image of the planet-deity must not, however, for the
above purpose, have an antique, but a mystic and ro-
mantic figure and dress. For jovial diseases one had
a talisman with the figure of Jupiter, which bore a per-
fect resemblance to an old professor of Wittenberg or
Basle. He was represented like a man with a beard,
in a wide gown lined with fur, holding in the one hand
an open book, and demonstrating with the right. I
should not have dwelt so long on the present subject,
had not this conceit of the last century been again
revived a few years ago by Cagliostro, and found par-
tisans here and there towards the end of the eighteenth.
The more ridiculous and abstruse these conceptions
were, the more respectable must be the memory of a
man who could fortunately rise superior to them, and
discover the art of prolonging life by pursuing the path
of temperance and of nature. Cornaro, who by the
simplest and strictest regimen, and an unexampled per-
severance in his plan, attained happily to a great age,

which rewarded him richly for his self-denial, and gave
an instructive lesson to posterity, was an Italian. One
cannot read the history of the life and abstinence of this
veteran of eighty-three, and hear how he praises that
serenity and contentment for which he was indebted to
his mode of living, without participating in his happi-
ness and his cheerful sensations. Till the fortieth year
of his age he had led a life of dissipation ; had been
always subject to colics, pains in his limbs, and a
fever ; and was so far reduced by the last, that his phy-
sicians assured him he could not live above two months ;
that all medicine would be useless ; and that the only
thing which could be recommended for him was a spare
diet. Having followed this advice, he found, after some
days, that he was much better ; and at the end of a few
years his health was not only perfectly reestablished,
but he became sounder than ever he had been befcre.
He resolved, therefore, to restrain himself more and
more, and to use nothing except what was absolutely
necessary for his subsistence. For sixty whole years
he took no more than twelve ounces of food, every thing
included, and thirteen ounces of drink daily. He
avoided also violent heat and cold, as well as passion ;
and by this uniform regimen he kept not only his body
but also his mind in such a state of equality that noth-
ing was able to derange them. When at a great age,
he lost an important lawsuit ; and though this disap-
pointment hurried two of his brothers to the grave, he
remained perfectly sound and resigned. He was once
thrown from a carriage and trod under the feet of the
horses, so that an arm and one of his feet were dislocated ;

14 ART OF PROLONGING LIFE.

but he caused them to be reduced, and, without the use
of any medicine, was soon restored to his former condi-
tion. But what is most worthy of remark, and what
proves how dangerous the smallest deviation from long
custom may be, is what follows. When he was eighty
years of age, his friends prevailed upon him, as his body
now required more nourishment, to make a little ad-
dition to his food. Though well aware that with the
general decay of strength the powers of digestion de-
crease also, and that in old age one Ought rather to les-
sen than increase the quantity of nourishment, he gave
way to their request, and raised his food to fourteen
and his drink to sixteen ounces. " Scarcely," says he,
" had I continued this mode of living ten days, when I
began, instead of being cheerful and lively as before, to
become uneasy and dejected, a burden to myself and to
others. On the twelfth day, I was seized with a pain
in my side, which lasted twenty-four hours ; and this
was followed by a fever, which continued with so much
violence for thirty-five days, that my life was despaired
of. But, by the blessing of God, and my former regi-
men, I recovered ; and now, in my eighty-third year, I
enjoy a happy state both of body and mind. I can
mount my horse without assistance; I climb steep hills ;
and I have lately written a play abounding in innocent
wit and humor. When I return home from a private
comp'any, or the senate, I find eleven grandchildren,
whose education, amusements, and songs are the delight
of my old age. I often sing myself along with them,
for my voice is now clearer and stronger than ever it was
in my youth ; and I am a stranger to those peevish and

morose humors which fall so often to the lot of old age."
In this happy disposition he attained to his hundredth
year ; but his example has never been imitated.*

There was a period when people in France seemed
to be so little acquainted with the value of blood, that
Louis XIII., in the last ten months of his life, was bled
forty-seven times ; and besides, he was made to take
two hundred and fifteen purgatives, and to use a glyster
two hundred and ten times. Soon after, attempts were
made, by a process directly contrary, that of filling the
veins with fresh youthful blood, to invigorate and pro-
long the life of man, and to remove incurable disorders-
This method was called transfusion : and the operation
was performed by opening two veins, and, by means of
a small pipe, conveying blood from the artery of an-
other living creature into the one vein, whilst the blood
was suffered to flow off through the other. Some success-
ful experiments of this kind had been made in England
upon animals ; and it is certain that some old, lame
beasts, sheep, calves, and horses, by filling their bodies
with the blood of a young animal, had acquired, at
least, after some time, sufficient activity and vigor ; nay,,
attempts were even made to inspire courage into tim-
orous animals by the blood of some wild and ferocious-
one. Encouraged by these experiments, people did not
hesitate to try if they could not restore men by the same
means. Dr. Denys and M. Emerez, at Paris, were in-
deed so fortunate as to cure a young man who labored
under a lethargy which had resisted all the power of

medicine, and during which he had been blooded twenty
times, by filling his veins with the blood of a lamb ; and
likewise a lunatic, by exchanging his blood for that of
a calf. But as only the most incurable and wretched
of mankind were chosen for these experiments, it soon
happened that some of them died during the operation ;
and since that time no one has ventured to try it.* It
has, however, been practised on animals here, at Jena,
with great success : and indeed it ought not to be en-
lirely rejected ; for, though the strange blood introduced
into our bodies must be soon converted into our own,
and much, consequently, cannot be hoped from it in re-

* Transfusion has now become a standard and most important
(Operation, and has been the means of saving many lives. It is
applied in cases of extreme loss of blood, wherein every other
proceeding but that of the restoration of the lost blood must
necessarily fail. The first idea of transfusion dates back to the
early part of the seventeenth century, and is mentioned in 1615,
by Andreas Libavius, in a work on the Transmutation of Metals.
In England, the operation was performed on animals, by Dr.
Lower and Mr. Edmund King, in the year 1666, and later in the
same year, after the news of Denys's success on the human sub-
ject. * Dr. Denys and M. Emerez were the first to apply transfu-
sion to man, and their first success was very wonderful; the
results, however, proved unsatisfactory, and the operation was
prohibited by parliament. Dr. Riva met with a like want of suc-
cess in Italy, and the operation was prohibited by an edict of the
Pope. It WAS reserved for Dr. Blundell to discover the secret of
its failure, and revive transfusion in this country; he pointed out
the impropriety of conveying the blood of animals into the human
system, and was the first to employ human blood for the purpose.
By paying attention to this rule, and the invention of suitable
apparatus, the operation may now be deemed perfectly safe ; a
result for which we are indebted to Dr. James Blundell, Dr.
Charles Waller, and Mr. Doubleday. EDITOR.

gard to renewing and prolonging life, the sudden and
unaccustomed impression made by new blood upon the
noblest of the vital organs, may still, in certain disor-
ders, particularly of the mind and nervous system, pro-
duce a great and salutary revolution.

The great Bacon, whose genius embraced every
branch of science, and who first pointed out to the hu-
man mind, which had long wandered amidst error, the
path to conduct it back to truth, this great man himself
thought the question respecting the prolongation of life
worthy of his attention and researches. His ideas on
this subject are bold and new. He considers life as a
flame, which is continually consumed by the surround-
ing atmosphere. Every body, even^the hardest, is by
this incessant evaporation decomposed and destroyed.
He thence concludes, that, by guarding against th's
consumption, and by renewing our juices from time to
time, life may be prolonged. For preventing external
consumption, he recommends in particular the cold
bath, and after bathing, that friction with oil and oint-
ments which was so much practised by the ancients.
To lessen internal consumption, he prescribes tranquil-
lity of mind, cooling food, with the use of opium and
opiates,* by which the too great vivacity of the internal
emotions will be moderated, and the wasting connected

* I trust that none of the readers of this book will be tempted
to make vise of opium or opiates, upon this prescription of
Bacon. That philosopher must have reasoned upon the theo-
retical properties of opiates as sedatives ; but practical observa-
tion proves them to be stimulants, and consequently means
which tend to increase " internal consumption " very powerfully.
The habitual use of opium and opiates would certainly have the
effect of shortening rather than of lengthening life. EDITOR.

with them will be retarded. But, to remedy the una-
voidable desiccation and corruption of the juices, the
attendant of increasing years, he considers the best
method to be to undergo every two or three years a
renovating process, which consists in first freeing the
body from all the old and corrupted juices, by spare
diet and cathartics ; and then again filling the dry ves-
sels with new juices, by means of choice refreshing
and nourishing food ; and thus, in the properest sense,
to renew and invigorate one's self periodically. The
truth contained in these ideas cannot be denied ; and,
with some modification, these precepts might at all
times be employed.

At present, men have made more progress in the
arts that shorten life than in that of prolonging it.
Abundance of quacks have appeared, and still appear,
who with astralish salts, gold tinctures, ethereal essences,
celestial beds, and the magic of magnetism, promise
to arrest the course of nature. It was, however, soon
found that the celebrated tea of long life, of the Count
de St. Germain, was only a very vulgar mixture of
sandal-wood, senna leaves, and fennel ; that the elixir
of life, so much boasted of by Cagliostro, was merely a
simple but very hot stomachic ; that the wonderful vir-
tue of magnetism depended on the combined effects of
imagination, nervous irritation, and sensibility; and
that the vaunted ethereal salts and gold tinctures con-
tributed more to benefit their inventor, than to prolong
the lives of those who employed them.

The phenomenon of magnetism deserves in a par-
ticular manner not to be omitted in this catalogue.
Mesmer, an enthusiastic physician, who becoming a

METHOD BY MAGNETISM. 19

bankrupt had fallen into contempt, and who, in all
probability, was not so much assisted by invisible pow-
ers as encouraged by negligent magistrates, at length
conceived the idea of making artificial magnets, which
he sold as a sovereign remedy for many diseases, such
as lameness, the gout, toothache, headache, etc. As he
found that this plan succeeded, he advanced a step
further, and asserted that he had no more occasion for
artificial magnets, but that he himself was the grand
magnet which should magnetize the world. His own
person, he pretended, was so filled with magnetic vir-
tue, that he could communicate it to another by the
touch, by stretching out his finger, and even by a single
look. He, indeed, produced instances of people, who,
being touched by him, or even looked at, declared they
had experienced sensations as if they had been struck
with a stick, or a piece of iron. This singular virtue
he called animal magnetism ; and he connected with
that strange appellation whatever is dearest to man,
life, wisdom, and health; which by these means he
could dispense and diffuse at his pleasure.

As he was not long permitted to propagate his en-
thusiasm at Vienna, he removed to Paris ; and it was
there that he first properly began to exhibit. He had
astonishing success ; every one wished to be cured by
him ; and all were desirous of participating in his virtue,
and of being able to perform miracles also. He estab-
lished a secret society, every member of which was
obliged to subscribe 100 louis d'ors ; and he at length
boldly declared that he was the man whom Providence
had chosen for the grand business of renovating human
nature, so visibly decayed. As a proof of what has

20 ART OF PROLONGING LIFE.

been here said, I shall lay before the reader only the
following address, which he caused to be made to the
public by one of his apostles : " Behold a discovery
which will bring invaluable advantages to mankind,
and eternal fame to its author ! Behold a general
revolution ! Other men will inhabit the- earth ; they
will be checked in their career of life by no weakness ;
and will be acquainted with our evils only by tradition !
Mothers will suffer less from the dangers of pregnancy
and the pains of childbirth ; and they will bring forth
stronger children, who will possess the activity, energy,
and courage of the old world. Animals and plants,
alike susceptible of . the magnetic virtue, will be free
from diseases ; flocks will more easily increase ; the
productions in our gardens will have more vigor ; the
trees will produce more beautiful fruit ; and the human
mind, in possession of this agent, will perhaps present
to Nature effects still more wonderful. Who can know
how far its influence may extend?"

One might imagine that one here read some of those
dreams of the middle ages ; but all these pompous
promises, and the prospects which they gave rise to,
instantly vanished, when a commission, at the head of
which was Dr. Franklin, had closely examined the
agency of this magnetism. The veil was withdrawn,
and nothing has remained of the whole deception ex-
cept animal electricity, and the conviction that it can
be put in activity by handling and stroking the body
various ways ; but it is certain that, without the help of
nervous weakness and enthusiasm, it will never produce
these wonderful phenomena, and that it is still less able
to prolong the life of man.

ANIMAL MAGNETISM. 21

It almost appears that mankind wish now to abandon
these ideas entirely to quacks, especially as the more
enlightened part make amends for the failure of this in-
vention, by having found that length of life does not
consist in number of days, but in the use and enjoyment
of it.

But as it is impossible that the one can make up for
the other, and as at present our acquaintance with the
nature of organized life, and the laws to which it is sub-
jected, has been enlarged and carried to greater perfec-
tion, it is worth while to employ this improved knowledge
in examining a matter of so much importance, and to
establish the method of prolonging life in such a manner,
on the principles of physics and animal economy, that
not only a more definite rule of life may be thence de-
duced, but also that this object in future may be ren-
dered of no use to quacks and impostors, who, as is well
known, can carry on their deceptions within the pre-
cincts of science only so long as they are not enlightened
by the torch of accurate investigation.

Inquiry into the nature of the vital power and the duration of life
in general. Properties and laws of the vital power. Definition of
life. Vital consumption inseparable consequence of vital opera-
tion. Term of life. Causes of the duration of life. Eetardation
of vital consumption. Possibility of prolonging life. Intensive and

THE first thing necessary in regard to the prolonga-
tion of life must undoubtedly be a more intimate ac-
quaintance with the nature of life, and in particular with
the vital power, the grand cause of all life.

May it not be possible, therefore, to investigate more
accurately the internal nature of that sacred flame, and
thence to discover by what it can be nourished, and by
what it is weakened ? I am perfectly sensible of the
boldness of this undertaking. I approach the sanctum
sanctorum of Nature ; and we have too many instances
of daring adventurers, who, blinded in such attempts,
were obliged to turn back with confusion ; and Hallcr
himself, her most intimate confidant, was forced to ex-
claim :

No mortal being, howe'er keen his eye,
Can into Nature's deepest secrets pry.

This, however, ought not* to deter us. Nature is, at
all times, a kind mother ; she loves and rewards those
who seek for her ; and though it may not always be

possible for us to reach the perhaps too exalted object
of our aim, we may, nevertheless, be certain to find, by
the way, so much new and interesting matter as will
amply reward us for attempting to approach nearer to
her. Let us only beware of forcing ourselves upon her
with too rash and precipitate steps; let our minds be
unprejudiced and open to conviction ; let our progress
be cautious ; let us ever be attentive to guard against
deception and phantoms of the mind ; and let our path,
if not the most convenient, be the certain path of expe-
rience and of regular proof; and let us shun the bolder
flights of hypothesis, which, in the end, generally prove
to the world that the wings which supported them were
cemented with wax. In this path we shall, with the
greatest certainty, avoid the fate of those philosophers
of whom Bacon says, with much justice, " They a.'e
night-owls, who see their visions in darkness, but be-
come blind in tlie light of experience ; and who per-
ceive least that which is clearest." By this path, and
with such a disposition of mind, the friends of Nature,
since the time of that great man, have approached
nearer to her than any one ever did before ; discoveries
have been made respecting her most hidden secrets ;
and her most concealed powers have been applied to
purposes which astonish the present age, and which will
still excite the wonder of posterity. By these means it
has been possible, through indefatigable research, even
without knowing the internal nature of things, to de-
termine and estimate her powers and properties so ac-
curately that we at least have a practical knowledge of
them, and can employ them for the uses of life. The
mind of man has thus been able to subdue even un-

24 ART OF PROLONGING LIFE.

known agents ; to direct them according to pleasure,
and render them of utility. The magnetic and the
electric power are agents which both elude our senses,
and whose nature will, perhaps, remain eternally un-
searchable ; yet we have rendered them so serviceable
to us, that by the one we can direct our course through
the ocean, and with the other kindle our night-lamp
while in bed.

I also, perhaps, shall be able to approach nearer to
Nature in the present research ; and I flatter myself
that the following method of treating my subject will be
the most proper to enable me to attain the object I have
in view : first, to define more accurately what is meant
by life and the vital power, and also to establish their
properties : next, to consult Nature respecting the dura-
tion of life in general, and that of different organized
bodies in particular ; to collect and compare examples ;
and, from the circumstances and situations in which the
life of a created being has a longer or shorter duration,
to draw a general conclusion in regard to the most prob-
able causes of the shortness or long duration of exist-
ence. After these premises, a more rational and satis-
factory answer may be given to the question, Whether
and in what manner the life of man can be prolonged ?

What is life ? and what is the vital power ? These
questions may be classed among many of the like kind
which occur to us during our researches into Nature..
They appear simple ; relate to the most common phe-
nomena; and are, however, difficult to be answered.
Wherever the philosopher uses the word Power, one
may always be assured that he labors under a difficulty,
since he explains a thing by a word which is itself a

NATURE OP THE VITAL POWER. 25

problem ; for, who has ever yet combined a clear idea
with the word Power ? In this manner has been intro-
duced into physics an infinite variety of powers: the
power of gravity, the power of attraction, the electric
power, the magnetic power, which, at bottom, signify
nothing more than the letter that expresses the unknown
quantity in algebra. We must, however, have expres-
sions for things whose existence is undeniable, though
their agency be incomprehensible ; and I hope I shall
be here permitted to use them, though it is not yet de-
termined whether what I treat of be really matter, or
only a property of it.

The vital power is, without dispute, one of the most
general, the most incomprehensible, and the most pow-
erful of all the powers of Nature. It fills and gives mo-
tion to every thing ; and, in all probability, is the graid
source from which all the other powers of the physical,
or at least the organized world proceed. It is that
which produces, supports, and renews every thing ; by it
the creation, after so many thousands of years, revives
every spring with the same freshness and beauty as
when it first came from the hand of its Maker. It is
inexhaustible and infinite, a real eternal emanation of
the Deity. In short, it is this which, purified and
exalted by a more perfect organization, kindles up the
powers of thought and of the soul ; and which gives to
rational beings, together with life, the sensation and
enjoyment of it. For I have remarked, that the sensa-
tion of the value and felicity of life is always very near-
ly proportioned to the greater or less abundance of the
vital power ; and that, as a certain overflow of it makes
one more capable of action and exertion, and of relish-

26 ART OF PROLONGING LIFE.

ing life, nothing is so capable as a want of it to produce
that misery and dejection which unfortunately distin-
guish the present age so much.

By accurate observation of its phenomena in the or-
ganized world, the following properties and laws of it
may be established :

1st. The vital power is the most subtle, the most pen-
etrating, and the most invisible agent of Nature, with
which we are as yet acquainted. In these respects it
exceeds light, electricity, and magnetism, to which, how-
ever, it seems to have the closest affinity.

2nd. Though it pervades every thing, there are cer-
tain modifications of matter to which it appears to have
greater relationship than to others. It unites, therefore,
with these in greater abundance, as well as in a more
intimate manner, and becomes, as it were, peculiar to
them. This modification of matter we call organic com-
bination, and structure of component parts ; and the
bodies which possess them we call organized bodies,
plants and animals. This organic structure seems to
consist in a certain disposition of the finest particles, and
we here find a remarkable similarity of the vital power
to that of magnetism ; as the latter, by a stroke given to
a piece of iron, in a certain direction, and which alters
the internal disposition of the finest component parts, is
immediately excited, and may be again destroyed by a
contrary derangement. That, at any rate, the organic
structure does not lie in the visible tissue or web, may
be seen in an egg, in which no traces of organized life
can be found, though it is certain that it there exists.

3rd. It can exist both in a free and a fixed state ; and
in this it has a great resemblance to fire and electricity.

NATURE OF THE VITAL POWER. 27

As these may reside in a body without manifesting them-
selves externally until they are called forth by a suita-
ble stimulus, the vital power, in like manner, may long
reside in a fixed state, in an organized body, without in-
dicating itself in any other way than by supporting and
preserving itself from dissolution. Of this we have
some astonishing instances. A grain of corn can retain
life in a fixed state for years, and an egg several months :
it neither evaporates nor corrupts ; and the stimulus of
heat alone can disengage the confined power, and call
forth the expansive principle of life. Nay, the already
expanding organic life can in this manner be again
checked and confined, yet exist some time in that state,
and preserve the organization intrusted to it, of which
the polypes and animal plants in particular afford us
the most remarkable instances.

4th. As it seems to have a different affinity to differ-
ent organized bodies, and abound more in some and less
in others, its union with some is likewise stronger, and
with others weaker. And it is worthy of remark, that,
where it abounds in the greatest quantity and perfection,
it seems there to be more loosely combined. To the
imperfect, weak-lived polype, for example, it adheres
with more force than to a more perfect animal in a
higher degree of existence. For the present inquiry
this observation is of the utmost importance.

5th. It gives to every body which it pervades an en-,
tirely new character, a specific superiority to other parts
of the corporeal world. In the first ' place, it renders
them susceptible of impressions as a stimulus, and
makes them capable of reaction ; and, secondly, it frees
them from the general physical and chemical laws of

28 ART OF PROLONGING LIFE.

inanimate nature : so that one may with propriety say,
by the assistance of the vital power a body is trans-
ferred from the mechanical and chemical world to a
new one, the organic or living world. Here the gen-
eral physical laws of Nature have place only in part,
and with certain limitations. All impressions in a liv-
ing body are modified and counteracted in a manner dif-
ferent from what they are in an inanimate body. In a
living body, therefore, no process merely mechanical or
chemical is possible ; and every thing assumes the char-
acter of life. A blow, or any stimulus, cold and heat,
act in a living body according to laws altogether pecu-
liar ; and in every effect thence produced must be consid-
ered as compounded of the external impression and the
reaction of the vital power.

In this lie the grounds of the peculiarity of different
species, and even of different individuals. We observe
daily that plants which grow near each other in the
same soil, and which receive the very same nour-
ishment, are widely different in their form, sap, and
properties. This is the case also in the animal king-
dom ; and hence the common expression, " every one
has his own peculiar nature."

6th. The vital power is the principal support of the
body in which it resides. It not only binds and keeps
together the whole organization, but it counteracts also,
very strongly, the destructive influence of the other
powers of Nature, so far as they depend on chemical
laws, which it is able to annihilate, or at least to mod-
ify. Among these, I reckon, in particular, the effects
of putrefaction, of the atmosphere, and of frost. No
living being putrefies ; a previous weakening or annihi-

NATURE OF THE VITAL POWER. 29

lation of the vital power is always necessary in order
to render corruption possible. Even in a fixed and
inactive state, it is able to keep off corruption. No-
egg, so long as it contains the vital power ; no grain of
corn, no silk worm inclosed in its cocoon, no insect ap-
parently dead, corrupts ; and it is truly astonishing how
it can preserve bodies which have such a strong ten-
dency to putrefaction as that of man has,, for sixty,,
eighty, or a hundred years. By its binding property it
withstands the power of the atmosphere, the second
cause of destruction, which, in the end, dissolves the-
hardest bodies, and makes them fall to pieces. In like
manner, the dangerous excitation of the particles of fire
keeps off frost. No living body freezes ; that is to say,
so long as its vital power is in activity, frost cannot
destroy it. Amidst the ice mountains of the South and
North pole, where all Nature appears to be in a state
of torpor, one sees living creatures, and even men, who
are not affected by the general congelation.* This
property of the vital power seems not confined merely
to its active, but belong also to its fixed state. An
egg, or a grain of corn, possessed of life, freezes much
later than one that is dead. The bear passes the whole
winter half torpid, among the snow; the apparently
dead swallow and the pupa? of insects continue under
the ice without being frozen. When the frost increases

* The galantlms nivalis, snowdrop, pushes itself from the frozen
earth through the snow, and its flower remains unhurt, notwith-
standing the severe night frosts. Mr. Hunter caused fish to be
frozen into water. As long as they lived, the water, though
congealed everywhere else, remained around them fluid, and
formed a real hole ; but as soon as they died, that part froze up
also.

30 ART OF PROLONGING LIFE.

so much as to weaken or oppress the vital power, it can
then, only, overcome it, and penetrate a living body.
This phenomenon depends in particular on that prop-
erty which the vital power possesses, of exciting warmth ;
as we shall see hereafter.

7th. A total loss of the vital power is attended with
a dissolution of the organized structure of the body
which it before filled. The matter of the body obeys
the laws and affinities of inanimate chemical nature, to
which it now belongs; its first principles are divided
and separated ; and corruption, under the usual circum-
stances, follows; which can alone convince us that a
body has been totally deprived of the vital power. But
it is a great and striking observation that corruption
itself, which seems to annihilate all life, must be the
means of calling forth new life again ; and that it is
properly nothing else than a highly important process
to disengage in the speediest manner the component
parts, no longer susceptible of life under that form, and
to make them fit for new organic combination and life.
No sooner is a body thus decomposed than its fine par-
ticles begin to be again animated in a thousand small
worms, or to display their revival under the figure of
beautiful grass : the most vivid flowers recommence, in
this manner, the great circle of organic life ; and, by a
few changes, become a year after component parts per-
haps of as perfect a human being as that with which
they appeared to corrupt. Their apparent death was
only a transition to a new life ; and the vital power
leaves a body only that it may unite itself again with
it in a more perfect manner.

8th. The vital power may be weakened, and even

NATURE OF THE VITAL POWER. 31

totally destroyed, by certain causes ; and by others can
be excited, strengthened, and nourished. Among those
which destroy it may be reckoned in particular cold, the
great enemy of all life. A moderate degree of cold,
however, can be so far strengthening, as it concentrates
the vital power and prevents its consumption : but this
strengthening is negative, not positive ; and a higher de-
gree of cold banishes it entirely. In cold, no vital
expansion can take place ; no egg can be hatched ; no
grain of corn shoot forth.

To these also belong certain derangements which
seem to have effect partly by annihilating the vital
power, and partly by a destructive alteration of the in-
ternal organized disposition of the particles. Thus a
violent electric shock, or lightning, deprives -plants and
animals of life, instantaneously, without leaving the
least trace of their having injured the organs ; and thus
among more perfect beings in particular, may the vital
power be destroyed, in a moment, by violent agitations
of the mind, such as sudden fear or joy.

Lastly, there are certain physical powers which are
highly capable of weakening and even of annihilating
it ; and these, therefore, we commonly call poisons : as,
for example, the smallpox infection, laurel water, the
essential oil of bitter almonds, etc.

But there are agents also of a contrary kind, which
have a friendship for, and an affinity to, the vital power ;
and which are capable of exciting, invigorating, and, in
great probability, of affording it a subtle nourishment.
These, in particular, are, light, heat, and air, or rather
oxygen, three celestial gifts, which, with great pro-
priety, may be called the friends and guardian spirits
of life.

32 ART OF PROLONGING LIFE.

LIGHT, the first of these, is, without doubt, the most
intimate friend and relation of life ; and, in this respect,
has certainly a much more essential effect than is com-
monly believed. The life of every created being is the
more perfect the more it enjoys the influence of light.
Let a plant or an animal be deprived of light, notwith-
standing every nourishment, care, and cultivation, it will
first lose its color, then its strength, and at last entirely
decay. Even man, who passes his life in darkness, be-
comes pale, relaxed, and heavy, and at length loses the
whole energy of life ; as is proved by the many melan-
choly instances of persons shut up in gloomy dungeons.
Nay, I do not think I say too much when I assert, that
organized life is possible only under the influence of
light, and in all probability through it ; for in the bowels
of the earth, in the deepest caverns, where eternal night
prevails, nothing is seen but what we call unorganized
life. There nothing breathes, there nothing feels ; and
the only productions which one finds are a few kinds of
mould and stone moss, the first most imperfect degree
of vegetation. For that reason, this vegetation, for the
most part, shows itself only on old or rotten wood. The
expansion of organized life must, therefore, be here ex-
cited by wood and water, or by that putrefaction which
generates life, and which in those abysses does not exist.

The second, no less beneficent friend of the vital
power, is HEAT, which is alone able to call forth the
first movements of life. When winter has reduced all
nature to a deathlike condition, let the genial warmth
of the spring atmosphere only breathe upon it, and all
its dormant powers are awakened to activity. The
nearer we approach the poles, every thing becomes

LIGHT AND HEAT. 33

deader, and we at length find districts where absolutely
no plant, insect, or small animal can exist, and where
only large masses of being, such as whales, bears, and
the like, can retain that warmth necessary for life. In
a word, where there is life there is heat, in a greater or
less degree ; and between both there is a very impor-
tant and inseparable connection. Warmth gives life,
and life again excites warmth ; and it seems difficult to
determine which is the cause, and which the effect.

Of the extraordinary power which heat has to nour-
ish and awaken life, the following entirely new and de-
cisive instance deserves to be mentioned. On the 2nd
of August, 1790, a carabinier, named Petit, threw him-
self, entirely naked, into the Rhine, from a window of
the military hospital at Strasburg. This circumstance
was observed about three o'clock in the afternoon ; and
the body remained above half an hour in the water be-
fore it was drawn out, to all appearance perfectly dead.
It was placed in a bed thoroughly warmed, with the
head raised up, the arms stretched out close to it on
each side, and the legs laid together. No other process
was employed than the application of warm cloths to
the stomach and legs. Warm stones, also, wrapped up
in cloth, were placed in different parts of the bed. In
the course of seven or eight minutes a small motion was
observed in the eyelids. A little while after, the under
jaw, which had been fast locked to the. upper one, be-
came loose ; the patient foamed at the mouth, and he
was able to swallow a few spoonfuls of wine. His pulse
now returned, #nd at the end of an hour he was able to
speak. Warmth, in cases of apparent death, acts evi-
dently with as much power as on the first expansion of
3

34 ART OF PROLONGING LIFE.

life : it nourishes the smallest sparks of the vital princi-
ple still remaining; fans them, and gradually rouses
them into a flame.

The third important nourisher of life is AIR. We find
no being that can live entirely without air ; and sud-
den, sometimes instantaneous, death is to most of them
the consequence of its being withdrawn. What makes
its influence highly visible is, that those animals which
breathe are more abundant in the vital power, and pos-
sess it in greater perfection, than those which do not
breathe. Dephlogisticated or empyreal air appears,
principally, to be that component part of our atmos-
phere which affords the strongest and best nourishment
to the vital power ; and in the present age, since the
wonder-working art of chemistry has taught us to pro-
duce it pure, people, on inspiring it, have experienced a
general sensation of strengthening and invigoration.
The grand principle of this empyreal or vital air is by
chemists called oxygen ; and this component part is that
properly which in the air which contains life, and passes
into the blood by breathing. Water, also, belongs to
the agents friendly to life, so far as it contains oxygen ;
and |t certainly promotes life, for without fluidity no ex-
pansion of life is possible.

I think I may with justice, therefore, assert, that
light, heat, and oxygen are the real proper nourishment
and sustenance .of the vital power. Grosser kinds of
nourishment, setting aside the quantity of oxygen and
empyreal matter which they contain, seem to serve
rather for supporting the organs and rep.airing the con-
sumption. Were not this the case, one could not ex-
plain how created beings can maintain life so long with-

PROLONGED ABSTINENCE. 35

out nourishment. Let us only consider the chicken in
an egg. It lives without the smallest external support ;
expands itself, and becomes a perfect animal. A hya-
cinth, or any other bulbous plant, can, without the least
nourishment except the evaporation of water ex-
pand and shoot forth a stem crowned with beautiful
leaves and flowers. Even among more perfect animals
we observe phenomena which would otherwise be inex-
plicable. Dr. George Fordyce, for example, inclosed
gold fish in vessels filled with well-water ; gave them at
first fresh water every twenty-four hours, but afterwards
only every three days ; and yet they lived fifteen months
without any nourishment, and, what is more wonderful,
became twice as big. But, as it might have been be-
lieved that the water contained a multitude of invisible
nutritive particles, he distilled it ; added air to it again ;
and, to prevent the introduction of insects, closed up
the vessels with great care. Notwithstanding all this,
the fish lived a long time, increased in size, and had ex-
cretions. How is it possible that man himself could
endure hunger so long and yet retain life, if the nutri-
ment of the vital power were necessarily derived from
the substances by which he is nourished ? A French
officer, after a tedious and severe illness, was seized
with a mental disorder, during which he resolved to
starve himself to death ; and he continued so firm to his
purpose that, for the space of forty-six days he did not
take the smallest grain of food. On the fifth day he
asked only for some distilled water ; and as half a pint
of anise-seed water was given to him, he used the whole
of it in three days. His friends, however, having rep-
resented to him that this quantity was too much, he put

36 ART OF PROLONGING LIFE.

into each glass of water that he drank no more than
three drops ; and in this manner his half-pint lasted till
the thirty -ninth day. He then gave over drinking, and
for the last eight days took nothing at all. After the
thirty-sixth day he was obliged to lie in bed ; and it is
remarkable that this man, extremely clean in other re-
spects, exhaled during the whole time of his fasting, a
very offensive smell, in consequence of the interrupted
renovation of his juices, and the corruption attending
it ; and that his eyes became weak. All advice proved
ineffectual, and his friends gave him up as lost, when
the voice of Nature was suddenly awakened within him
by an accident. He saw a child with a piece of bread
and butter enter the apartment where he was. This
sight excited his appetite so much at once that he begged
for some soup. A few spoonfuls of rice broth were now
given him every two hours ; some stronger food was
gradually added ; and his health, though slowly, was in
this manner again wholly restored. But it is very sin-
gular that while he fasted and was weak, his phrensy
and wild imaginations forsook him, and that he answered
when addressed by his usual name ; but as soon as he
had acquired strength by eating, his whole train of in-
coherent ideas again returned.*

9th. There is still a cause which tends to weaken and
diminish the vital power, and which lies in itself, namely,
the loss it sustains by exerting its strength. By every
exertion it loses some of its force ; and when these ex-
ertions are too violent, or continued without intermis-
sion, the consequence is that it may be completely ex-
hausted. This is proved by common experience, as we

* See Hist, de 1'Acade'mie Royale des Sciences. 'An. 1769.

NATURE OP THE VITAL POWER. 37

find that, after great exertion in walking, thinking, etc.,
we become fatigued. It is shown still more clearly by
the experiments of Galvani, in which, after death, a
muscle and nerves, still alive, may be irritated by the
application of metal. If this irritation be often and
strongly repeated, the power will be sooner exhausted ;
but if slowly, it will be exhausted later : and even when
it appears to be totally exhausted, one, by intermitting
the irritation for some time, can occasion a new accu-
mulation of it, and produce fresh exertions. Hence
arises a new means of strengthening, namely, rest, or a
suspension of exertion, by which indeed the power can
be accumulated and increased.

10th. The most immediate functions of the vital
power are not only to receive impressions, such as irri-
tation, and to react upon them, but also to change into
organized nature the component parts which are added
to the body ; that is, to unite them according to the laws
of organization, and also to give them that structure and
form which the end of organization requires.

llth. The vital power pervades all the parts of an
organized living body, whether fluids or solids ; but it
manifests itself in different ways, according to the differ-
ence of the organs ; in the nerves, by sensibility ; in the
muscles, by irritability, etc. This it does for some time
visibly and without interruption, and is what we name
generation or growth, until the organized body has at-
tained to its destined degree of perfection. This plas-
tic, creative power, does not, however, cease to act ; but
what was before growth, becomes now constant renova-
tion ; and this incessant regeneration is- one of the most
important means which support the being.

38 ART OF PROLONGING LIFE.

These observations on the nature of this wonderful
power are sufficient. It will now be easier for us to
speak in a more precise manner on the influence
which this power has on life ; to explain what life
properly is ; and to say something decisive concerning
its duration.

LIFE, in an organized being, means the free active
state of the before-mentioned power, and the activity
and efficiency of the organs inseparably connected with
it. The vital power, therefore, is only capacity ; life
itself, action. Every life, consequently, is a continued
operation of the efficiency of the power and of organic
exertion. A continual consumption of the power and
of the organs is necessarily the immediate consequence
of this process ; and, on that account, an incessant reno-
vation of both is requisite in order that life may be
supported. The process of life may then be considered
as a continued process of consumption ; and its essence
may be defined an uninterrupted wasting and repara-
tion of ourselves. Life has been already often com-
pared to a flame ; and indeed the operation in both is the
same. Destructive and creative powers are engaged,
with never-ceasing activity, in a continual struggle
within us ; and every moment of our existence is a sin-
gular mixture of annihilation and new creation. As
long as the vital power retains its freshness and energy,
the living plastic powers will have the superiority, aj?d
afford it protection in this contest : the body will also
increase and approach nearer to perfection. By
little and little they will balance each other, and,
the consumption becoming equal to the renovation, the
body will at length decrease. At last, the vital power

NATURE OP LIFE. 39

being lessened, and the organs worn out, the consump-
tion will begin to exceed the renovation ; and decay,
degradation, and, in the end, a total dissolution will un-
avoidably follow. This is universally the case. Every
created being passes through three periods: that of
its growth, that of its being stationary, and that of its
decline.

The duration of life, in general, depends on the fol-
lowing points :

1. On the quantity of the vital power which resides
in the being. A greater supply of the vital power will
naturally last much longer, and be later consumed, than
a smaller. Now we know, from what has been before
said, that the vital power has a greater affinity to some
bodies, and to others a less ; that it abounds much more
in some than in others ; and that many external causes
tend to weaken it, and many to nourish it. This, there-
fore, gives us the first and most important ground of the
difference in the duration of life.

2. But, besides the vital power, the organs also are
consumed and wasted by living ; and, consequently, a
total consumption must take place later in a body the
organs of which are strong, than in one of a delicate
structure more liable to dissolution. Besides, the ope-
ration of life itself requires the continual agency of cer-
tain organs, which we therefore call the vital organs.
If these be diseased, or unfit for use, life cannot continue.
A certain firmness of organization, and a proper con-
dition of the vital organs, form the second ground on
which the duration of life depends.

3. The process of consumption may be carried on
more slowly, or more rapidly ; and, consequently, the

40 ART OF PROLONGING LIFE.

duration of it, or what we call life, even when the pow-
ers and organs are perfectly alike, will be longer or
shorter in proportion to the quickness or slowness of the
operation; just as a candle lighted at both ends at the
same time burns twice as fast as one lighted in the
usual manner, or as a light in oxygen gas is consumed
ten times faster than one of the same kind in common
air, because by that medium the process of consumption
is increased and accelerated in a tenfold proportion.
This affords the third ground of difference in the dura-
tion of life.

4. As renovation of what is lost and continual regen-
eration are the principal means of counteracting the
consumption, those bodies which internally and exter-
nally have the best means of regenerating themselves
with most ease, and in the greatest perfection, will natu-
rally be of longer duration than those which are desti-
tute of that advantage.

In short, the duration of life in a being will be pro-
portioned to the innate quantity of vital power, the
greater or less firmness of its organs, the speedier or
slower consumption, and perfect or imperfect restoration.
All ideas on the prolongation of life, as well as all the
means which have been or may be proposed on that
subject, can be brought under these- four classes, and be
examined upon these principles.

From these, several important deductions may be
made, and several obscure questions may be answered,
of which I shall only mention a few.

Is the extent of life determined or not ? This question
has oft given rise to disputes in which divines and phi-

DURATION OF LIFE. 41

losophers have been divided, and which have several
times brought the medical art into great difficulties. On
the above principles, however, it may be easily resolved.
Each raqe of beings, as well as each individual, has its
term of life as certainly fixed as it has its defined size,
and its proper quantity of vital power, strength of
organs, and means of consumption or regeneration ; for
the duration of life is a consequence of that consump-
tion, and can continue no longer than power and organs
are able to support it. But this consumption may be
hastened or retarded : favorable or unfavorable, destruc-
tive or beneficial circumstances may have an influence
upon it ; and it thence follows that, notwithstanding the
before-mentioned natural determination, the limits of it
may be altered.

A general answer may now be given also to the fcl-
lowing question : Is it possible to prolong life ? Un-
doubtedly it is ; but not by magical cures or gold tinc-
tures ; nor can we hope to increase the quantity and
efficacy of the vital power which has been dispensed to
us, or to alter the whole determination of Nature.
Whatever is done must be effected by proper attention
to the above four points, on which the duration of life
properly depends ; by strengthening the vital power
and the organs ; by retarding consumption, and by pro-
moting or facilitating renovation or regeneration. The
more food, clothing, manner of living, climate, and even
artificial means are favorable to these requisites, the
more influence they will have in the prolongation of
life ; the more they counteract these, the more will they
shorten the duration of existence.

What I call retardation of vital consumption, as being,

42 ART OF PROLONGING LIFE.

in my opinion, the most important means of prolonging
life, deserves here, in a particular manner, to be con-
sidered. If we suppose that each body is possessed of
a certain quantity of vital power, and certain organs
which make as it were our stock of life, and that life
consists in a consumption of them, it must be allowed
that this stock may be naturally consumed by a stronger
exertion of the organs, and by the speedier wasting
which is connected with it. He who in a day consumes
twice as much of the vital power as another, will ex-
haust his stock sooner ; and organs used with double
force will in half the time be worn out and become
useless. The energy of life, therefore, will be in an in-
verse ratio with its duration ; or the more intensively a
being lives, the more will its life lose in extension. The
expression, fast living, which, as well as the thing itself,
is at present so common, is not then altogether improper.
One may certainly make the process of vital consump-
tion, whether it consists in labor or enjoyment, more or
less rapid, and thus live either fast or slowly. In fu-
ture I shall distinguish the one by the expression inten-
sive life, and the other by that of extensive life. This
truth is confirmed, not only among men, but also through-
out all nature. The less intensive the life of a being is,
the longer will be its duration. If the intensive life of
a plant be increased by heat, manure, and artificial
means, it will expand itself to perfection more rapidly,
but it will also soon decay. Even a being which natu-
rally possesses an abundant stock of vital power will,
when its life is intensively active, be of shorter duration
than another less abundant in vital power, but which
has by nature a life less intensive. Thus it is certain,

INTENSIVE AND EXTENSIVE LIFE. 43

for example, that the higher classes of animals have the
vital power in far greater quantity and perfection than
vegetables ; yet a tree lives a hundred times as long as
the spirited horse, because the life of the tree is inten-
sively weaker. In this manner, weakening circum-
stances, when they only lessen the intensive activity of
life, may be the means of prolonging it ; and, on the
other hand, influences which strengthen and excite life,
when they increase the internal activity too much, may
be prejudicial to its duration. Hence it is evident how
very sound health may shorten the duration of life, and
a certain kind of weakness be the best means of pro-
longing it ; and that the diet and means used for length-
ening life, cannot be altogether those which are com-
monly called corroborative. In this respect, Nature
herself gives us the best lesson, as she has connected
with the existence of every more perfect being, a cer-
tain regulation which is able to check the stream of its
vital consumption, and thereby prevent too rapid
wasting. I here allude to sleep, a condition which
takes place in every animal of a perfect kind : a dispo-
sition of the utmost wisdom, which, in directing and
retarding the vital consumption, acts in the same man-
ner as the pendulum of a clock. The time of sleep
is nothing else than a suspension of intensive life, or an
apparent loss of it ; but even in this suspension, this
interruption of its activity, lies one of the greatest
means of preserving it. A twelve or sixteen hours'
uninterrupted continuation of intensive life, causes such
an impetuous stream of consumption as produces a more
violent pulse, a kind of general fever, the so-called daily
evening fever. Sleep then comes to the relief of the

44 ART OP PROLONGING LIFE.

body ; reduces it to a more passive condition ; and after
a seven or eight hours' pause of this kind, the destruc-
tive stream of vital consumption is so much checked ;
what has been lost is so fully renewed, that pulsation
and all its other movements are again performed slowly
and regularly, and every thing proceeds with a peace-
ful course as before.* Nothing, therefore, is able to
waste and destroy us so speedily as long continued
want of sleep. Trees even, those Nestors of the vege-
table kingdom, without the annual sleep of winter,
would not be able to preserve their lives so long.f

* Old people, therefore, sleep less, because their intensive life,
or vital consumption, is weaker, and requires less restoration.

t In many plants we even find something which may with
great propriety be compared to the daily sleep of man. Their
leaves every evening are contracted, or droop ; their flowers shut
themselves up, and their whole external appearance displays a
state of rest and repose. Some have ascribed this to the coolness
and moisture of the evening ; but the same thing takes place also
in the greenhouse. Others have considered it as a consequence
of darkness ; but many shut themselves up in summer at six
o'clock in the afternoon. Nay, the tragopogon luteiim shuts itself
up so early as nine in the morning ; and this plant, therefore,
gives us reason to compare it to certain night birds and beasts of
the animal world, which are active only during the night, and
sleep in the daytime. Every hour of the day, even, has some
plant which then shuts itself up, and on this is founded what is
called a, plant-dial.

Duration of the life of plants ; diversity of it. Annual, biennial,
perennial. Experiments respecting circumstances by which this
is determined; result of them. Application of the fundamental
principles of the duration of life. Great influence of attention and
culture on the duration of the life of plants.

IN order to prove and confirm what has been before
said, let me now be permitted to take a view of all the
classes of the organized world, and endeavor to estab-
lish on solid principles what I have asserted. This will
give us an opportunity of becoming acquainted with the
most important collateral circumstances which have an
influence in prolonging or shortening life. How infi-
nitely various is the duration of the different organized
beings ! Between the mould, which lives only a couple
of hours, and the cedar, which can attain to the age of a
thousand years, what a difference ; how numberless the
intermediate degrees ; what a variety of life ! The
grounds, however, of this longer or shorter duration
must lie in the structure of each being. This is an im-
portant and interesting circumstance, but at the same
time of the utmost extent. I must, therefore, content
myself with deducing from it the principal data, and
exhibiting them in our present point of view.

In this respect, plants, that immense world of crea-
tion, that first degree of organized beings which nourish
themselves by internal appropriation, form an indi-

46 ART OF PROLONGING LIFE.

vicinal and propagate their race, first present them-
selves to our view. What infinite variety of shape,
organization, size, and duration ! According to the latest
discoveries and calculations, they amount to forty thou-
sand genera and species at least !

They may all, however, be reduced, according to their
duration of life, into three principal classes : annual, or
properly only semi-annual, which grow up in spring, and
die in autumn ; biennial, which die at the end of the
second year; and, lastly, perennial, the duration of
which extends from four to a thousand years.

All plants of a soft watery constitution, and which
have fine tender organs, have a short life, and last only
one or at most two years: those alone which have
stronger organs and tougher juices exist longer; but
wood is absolutely necessary in order to attain to the
highest degree of vegetable existence.

Even among those which live only one or two years
a remarkable difference may be observed. Those which
are of a cold insipid nature, and destitute of smell, live,
under like circumstances, not so long as the strong-
scented, balsamic plants, which contain more essential
oil and spirits. Lettuce, wheat, oats, barley, and all
kinds of corn, live no more than 'a year ; but, on the
other hand, thyme, mint, hyssop, balm, wormwood, mar-
joram, sage, etc., can live two years, and even longer.

Shrubs and small trees can live sixty years, and some
even twice that number. The vine attains to sixty or
a hundred years, and continues fruitful at the greatest
age. This is the case also with rosemary. The acan-
thus and ivy, however, can exceed the age of a hundred.
Among many, such, for example, as the different kinds

of rubus,* it is difficult to determine the age, as the
branches creep along the ground, and always form new
plants, so that it is almost impossible to distinguish the
new from the old ; and by these means they make their
existence as it were perennial.

Those which attain to the highest age are the great-
est, strongest, and hardest trees ; such as the oak, the
lime-tree, the beech, the chestnut, the elm, the plane-
tree, the cedar, the olive, the palm, the mulberry-tree,
and the baobab.f We may with certainty affirm, that
some of the cedars of Lebanon, the celebrated chestnut-
tree di centi cavalli in Sicily, and several of the sacred
oaks under which the ancient Germans performed their
religious ceremonies, may have attained to the age of a
thousand years and more. These are the most venera-
ble, the only now existing testimonies of the ancient
world, and inspire us with reverence and awe when the
rustling wind plays through their silvery locks, which
once served to overshade the Druids and our wild an-
cestors clothed in their bearskins.

All trees of a rapid growth, such as the fir, the birch,
the horse-chestnut, and the like, yield always less solid
and durable wood, and the period of their existence is
shorter. The oak, which is the slowest in growing of

t This newly discovered tree (Adansonia digitata) seems to be
one of those which live to the greatest age. Its trunk acquires
the thickness of twenty-five feet in diameter ; and Adanson, in
the middle of the present century, found trees only six feet in di-
ameter, which had cut on them the names of seafaring people
who had visited them in the fifteenth and sixteenth centuries, yet
these incisions had become very little extended.

48 ART OF PROLONGING LIFE.

all, has the hardest wood, and its life is of the longest
duration.

Smaller vegetables have, in general, a shorter life
than those which are large, tall, and spreading.

Those trees which have the hardest and most durable
wood are, however, not always those which live longest.
The beech, for example, the cypress, the juniper, the
walnut, and the pear-tree, do not live so long as the
lime-tree, though its wood be softer.

Those which produce juicy, tender, and delicate fruit,
are, in general, shorter-lived than those which are bar-
ren, or which bear fruit entirely useless. And among
the former, those which bear nuts or acorns become
older than those which produce berries and fruit with
stones.

Even these short-lived trees, the apple, the pear, the
apricot, the peach, the cherry, etc., can, under very fa-
vorable circumstances, prolong their life to sixty years ;
especially when they are freed from the moss which
grows upon them.

We may establish it as a general rule, that those trees
which are long in producing leaves and fruit, and which
also do not soon lose them, become older than those in
which both these changes take place speedily. Those,
likewise, which are cultivate'd, have, in general, a shorter
existence than those which grow wild ; and those which
produce sour, harsh fruit, live longer than those which
produce sweet.

It is highly worthy of remark, that when the earth is
dug up every year around the roots of a tree, it becomes
more vigorous and fruitful ; but the duration of its life

LIFE IN THE YEGETABLE KINGDOM. 49

is shortened. On the other hand, if this be done only
every five or ten years, it will live the longer. In the
like manner, frequent watering and manuring promotes
fruitfulness, but it injures the duration of life.

One, also, by frequently lopping off the branches and
buds, may contribute very much to the duration of the
life of a shrub ; so that small, shortlived plants, such as
lavender, hyssop, and the like, if annually pruned, may
prolong their life to the age of forty years.

It is also to be remarked, that when one turns up the
earth, which has remained long untouched and un-
changed, around the roots of old trees, and makes it
softer and looser, they will produce fresher and more
vigorous leaves, and become, as it were, again young.

When we consider with attention these observations,
derived from experience, it is perfectly evident how much
they confirm the above established principles of life and
vital duration, and that they coincide perfectly with
these ideas.

Our first grand principle was : the greater the quantity
of vital power, and the solidity of the organs, the longer
will be the duration of life ; and we now find in Nature
that the greatest, the most perfect, and the best-formed
productions, in which, also, we must allow the greatest
abundance of the vital power, and those which have the
strongest and most durable organs, are precisely those
which enjoy the longest life ; as, for example, the oak
and the cedar.

The bulk of the corporeal mass evidently appears here
to contribute to the duration of life, and on the three fol-
lowing grounds :

4

50 ART OF PROLONGING LIFE.

I. Bulk shows a greater provision of the vital or plas-
tic power.

II. Bulk gives more vital capacity, more surface,
more external access.

III. The greater mass a body has, the more time is
required before it can be wasted by its external and in-
ternal consumptive and destructive powers.

We, however, find that a plant may have very strong
and durable organs, and yet not live so long as one the
organs of which are of less solidity. Of this we have an
instance in the lime-tree, which lives much longer than
the beech or the cypress.

This now leads to a law of the utmost importance for
organized life and our future research ; which is, that,
in the organic world, a certain degree only of solidity
promotes the duration of life, and that too high a degree
of tenacity shortens it. In general, however, and among
unorganized beings, it is undoubtedly certain, that the
more solid a body is, the greater will be its duration ;
but in organized beings, where the" duration of existence
consists in continual activity of the organs and circula-
tion of the juices, this observation is limited, and too
great a degree of solidity in the organs, and toughness
in the juices, makes them sooner immovable and unfit
for discharging their functions, produces obstructions,
and brings on premature old age, and even death.

It is not, however, merely on the quantity of the
power and the organs that the vital power depends.
We have already seen that a great deal, in particular,
depends on the speedier or slower consumption, and on

LIFE IN THE VEGETABLE KINGDOM. 51

perfect or more imperfect restoration. Is this, there-
fore, confirmed in the vegetable kingdom ?

It is, in the fullest manner ; and we here find this
general law : the more intensive life a plant has, the
stronger and speedier is its internal consumption, the
sooner it decays, and the shorter is its duration : on the
other hand, the more capacity a plant has, either inter-
nally or externally, to, regenerate itself, the longer it
will preserve its existence.

I shall now proceed to treat, in the first place, on the
law of consumption. Plants in general have a very
weak intensive life, which consists only in the functions
of growth, propagation, and receiving nourishment.
They are subject to no arbitrary changing of place, no
regular circulation, no muscular or nervous motion.
The function of generation is, beyond dispute, the high-
est degree of their internal consumption, the utmost
stretch of their intensive life. But how speedily is it
followed by decomposition and annihilation! Nature
appears here to make, as it were, the greatest exertion
of her plastic power, and to show the ne plus ultra of the
highest finishing and of bringing to perfection.

What tenderness and delicacy in the structure of the
flower ; what elegance and splendor of colors astonish
us often in the most inconsiderable plant, to which we
never could have ascribed such expansion. These are,
as it were, the dress of ceremony, with which the plant
celebrates its greatest festival, but with which it also
often exhausts its whole stock of vital power, either for
ever, or at least for a long time.

All plants, without exception, lose, immediately after
this catastrophe, the vigor of vegetation ; and begin to

52 ART OF PROLONGING LIFE.

be stationary, which is the commencement of their dis-
solution. In all annual plants complete death follows ;
among the larger plants and trees, a temporal death at
least, or a torpor of half a year, until, by the great
strength of their regenerating power, they are again put
in a condition to shoot forth new leaves and flowers.

On the same principles it may be explained, how all
plants which acquire early the power of generation die
also soonest ; and it is an invariable law for the dura-
tion of life in the vegetable kingdom, that the earlier
and speedier a plant comes to flower, the shorter time
will its life continue ; but the later it flowers, its exist-
ence will be of the longer duration. All those which
flower immediately, the first year, die also the same
year; and those which flower for the first time the
second year, die also the second. Those trees only, and
woody shrubs, which first begin to generate in the sixth,
ninth, or twelfth year, become old ; and among these,
those genera which arrive latest at the period of propa-
gation become likewise the oldest. A highly important
observation, which, in part, fully confirms my ideas of
consumption, and gives an instructive hint in regard to
our future research.

An answer may now be given to that important ques-
tion, What influence has cultivation on the longer or
shorter duration of the life of plants ?

Culture and art, upon the whole, shorten life ; and it
may be admitted as a fundamental principle, that in gen-
eral all wild plants, left to themselves, live longer than
those which are cultivated. Every kind of culture, how-
ever, does not shorten life ; for, by careful attention, a
plant which lives only one or two years in the open air,

EFFECTS OF CULTIVATION. 53

may be preserved much longer : and this is a very re-
markable proof, that, even in the vegetable kingdom, it
is possible to prolong life by a certain kind of treatment.
But the question now is, In what consists the difference
of that culture which prolongs life, and that which short-
ens it ? This may be of importance to us in the follow-
ing research, and may be referred to our first fundamen-
tal principle. The more cultivation strengthens intensive
life and internal consumption, and at the same time
makes the organization more delicate, the more is it pre-
judicial to the duration of life. This we observe to be
the case in all hothouse plants, which, by warmth, ma-
nure, and other arts, are forced to a continual internal
activity ; so that they produce earlier, oftener, and more
exquisite fruit than is natural for them. The case is
the same, when, without forcing, by external causes, a
higher degree of perfection and delicacy than belonged
to its nature is communicated to the internal organiza-
tion of a plant, merely by certain operations and arts,
such, for example, as ingrafting, propping, and the art
used in regard to full flowers. This kind of culture
shortens the duration also.

Cultivation, on the other hand, may be the greatest
means of prolonging life, if it do not strengthen the in-
tensive life of a plant, or if it retard and moderate in
any manner its internal consumption ; if it lessen the
too great natural toughness or hardness of the organs or
matter to such a degree that they continue longer plia-
ble and proper for their functions ; and if it keep off
destructive influences, and supply it with better means
of regeneration. Thus, by the help of culture, a being

54 . ART OF PROLONGING LIFE.

may attain to a greater extent of life than it could have
acquired according to its natural state and destination.

The duration of the life of plants may be prolonged,
therefore, in the three following ways :

1st. If, by often pruning the branches, we guard
against too rapid consumption. By these means we de-
prive the plant of a part of those organs by which it
would exhaust too speedily its vital power, and we con-
centrate the power as it were within it.

2nd. If we thereby check, or at least retard its flower-
ing, and prevent a waste of the power of generation.
This, we know, is the highest degree of vital consump-
tion among plants ; and we thus doubly contribute to
the prolongation of life first, by preventing this power
from being exhausted; and, secondly, by obliging it to
return back and to act as a means of support or nourish-
ment.

3rd. If we keep off the destructive influence of frost,
the want of nourishment, and an irregular atmosphere,
and preserve it by art, in an uniform, moderate, mean
condition. Though we hereby somewhat increase the
intensive life, we nevertheless create a richer source of
regeneration.

Lastly, the fourth grand point on which the duration
of every being, and also of a plant, depends, is its greater
or less capacity to restore itself and to renew its parts.

In this respect, the vegetable world may be divided
into two grand classes. The first do not possess this
capacity; and these are the annual plants, or those
which live only a year, and which die immediately aft/er
they have performed the function of generation.

EXTENSION OF LIFE IN PLANTS. 55

The second class, on the other hand, which possess
this great faculty of regenerating themselves annually ;
of producing new leaves, branches, and flowers, can at-
tain to the astonishing age of a thousand years and
upwards. Such plants may be considered as organized
masses of earth, from which an immense number of
plants, but perfectly analogous to each mass, spring out
every year. And in this regulation the wisdom of Na-
ture appears great and divine.

When we reflect that, as experience teaches us, a
period of eight or ten years is required in order to pro-
duce that degree of perfection in the organs and in the
purification of the juices necessary in a tree before it can
bring forth flowers and fruit, if it were subjected to the
same laws of decay as other vegetable productions, and
if a tree died immediately after it had generated, ho^v
ill-rewarded would the culture of it be ; and how little
proportion would the expense of preparation and time
bear to the result ! In such a case, fruit indeed would
be uncommon.

To guard against this, Nature has wisely established,
that the first plant acquires gradually such a consistence
and solidity that, at last the place of the earth is sup-
plied by the trunk, from which an abundance of new
plants spring out every year under the form of buds and
buttons.

By this a double advantage is obtained. First, be-
cause these plants spring from a mass of earth already
organized, they immediately receive juices assimilated
and prepared, and can therefore employ them in the
production of flowers and fruit, which with sap derived
immediately from the earth would be impossible.

56 ART OF PROLONGING LIFE.

Secondly, these delicate plants, which in reality we
may consider as so many annuals, die again after the
process of fructification is completed, and yet the vege-
table itself, or the stem, continues perennial. Nature,
therefore, remains here true to her fundamental law,
that the function of generation exhausts the vital power
of single individuals, and yet the whole is perennial.

In a word, the result of all these observations is, that
the great age of a plant depends on the following
points :

I. It must grow slowly.

II. It must propagate itself slowly, and late.

III. It must have a certain degree of solidity and
duration in its organs, a sufficiency of wood, and the sap
must not be too watery.

IV. It must be large, and have considerable exten-
sion.

V. It must rise into the atmosphere.

By the contrary of all these the duration of life is
shortened.

THE animal kingdom, or second grand class of the
more perfect part of the organized world, is immensely
rich in being, and in variety and diversity of duration.
Between the elephant, which attains to the age of a hun-
dred years, and the ephemeron, that small perishable
insect, which exists scarcely a day, and which in the
twentieth hour of its life is an experienced veteran
among its numerous posterity, there are innumerable
intermediate degrees of vital capacity and duration ; but
amidst this vast abundance I shall content myself with
collecting only such data as may serve to illustrate our
principal question, On what does the duration of life de-
pend?

To begin with worms, the most imperfect class of all,
which approach very near to plants ; these, on account
of their tender, soft nature, can be injured and destroyed
with remarkable ease ; but, like plants, they have the
best support in their extraordinary power of reproduc-
tion, by which they can renew whole parts. Nay, when

58 / ART OF PROLONGING LIFE.

divided into two or three pieces they can still live, and
it is consequently difficult to determine their duration.

In this class 'there are some animals which almost
appear to be indestructible, and with which Fontana
and Gotze made so many important experiments. The
former caused wheel-insects and hair-worms to be dried
in the hot scorching sun, and to be parched in an oven ;
and at the end of half a year he was able to revive
these dried animals by pouring over them a little luke-
warm water.

These experiments confirm our position that the more
imperfect the organization, the stronger is the life. The
case here is the same as in the seeds of plants ; and one
may say that these first points of the animal creation
are, in a certain measure, only the first shoots or seeds
for the more perfect animal world.

Among those insects which have more of the animal,
and a more finished organization, the power pf repro-
duction cannot perform such wonders. But Nature
here has fallen upon another wise establishment, which
evidently prolongs their existence ; I mean that of meta-
morphosis or transformation. The insect exists, per-
haps two, three, or four years, as a larva or worm ; it
then becomes a pupa or nymph, and exists again in that
deathlike state a considerable time, at the end of which
it appears a completely finished being. It now first has
eyes, a winged, often an elegant body ; and what stamps
it principally with the mark of perfection, it is now first
rendered fit for generation. This state, which may be
called the time of its bloom, is, however, the shortest ;
it soon dies ; for it has attained to the end of its desti-
nation.

DURATION OF LIFE IN ANIMALS. 59

I cannot here omit to remark, how much these phe-
nomena coincide with the principles I laid down as the
grounds on which the duration of life depends. In its
first state as a worm, how imperfect its existence, and
how little its motion ! It is impossible for it to gene-
rate, and its whole faculties seem to consist in those of
eating and digesting ; for some caterpillars have so
monstrous an appetite, that, in the course of twenty-
four hours, they devour more than three times the
weight of their bodies. Their self-consumption, then,
must be exceedingly small, and their restoration prodi-
gious. It need excite no surprise, therefore, that, in
this condition, notwithstanding their diminutive size and
imperfection, they can live so long. The case is the
same in regard to their intermediate state as a chrysa-
lis, when the animal lives without nourishment, and it
consumed neither externally nor internally. But in the
last period of its existence, of its completely formed state
as a winged ethereal being, its whole life seems to consist
in continual motion and removal from one place to
another; yet, though its self-consumption is incessant,
we cannot think of nourishment or restoration, for many
butterflies in this condition have no mouth. With such
a refinement of organization, such a disproportion be-
tween what is added and what is taken away, no dura-
tion is possible ; and it is confirmed by experience that
the animal soon dies. Here, therefore, the same being
exhibits to us, in a very evident manner, a picture of
the most perfect as well as most imperfect life, and of
the longer or shorter duration connected with them.

Amphibia, those cold transition beings, can prolong

60 ART OF PROLONGING LIFE.

their existence to an extraordinary length ; an advan-
tage for which they are principally indebted to the tena-
city of their life, that is, to the very intimate and diffi-
cult to be dissolved connection of the vital power with
the material part, and the weakness of their intensive
life.

Of the tenacity of life we have instances truly aston-
ishing. Tortoises have been seen to live a considerable
time without the head ; and frogs, when their hearts
were torn out, have still continued to leap about. A
tortoise has existed six whole weeks without any food ;
and this sufficiently shows how small its intensive life
is, and how little need it has of restoration. Nay, it is
proved that toads have been found alive inclosed in
stones and blocks of marble-* Whether they were
shut up there in the egg, or as perfect beings, both
cases are equally astonishing ; for what a number of
years must have been necessary for the marble to gene-
rate, and before it could acquire its solidity !

This shows how much influence the power of regene-
ration has in prolonging life. A great many dangers

* In the year 1733, a toad was found in Sweden, seven ells
deep, in a quarry, in the middle of a block of the hardest stone,
to which people were obliged to force their way, with much labor,
by means of chisels and the hammer. It was still alive, but ex-
ceedingly weak. Its skin was shrivelled, and covered here and
therewith a stony crust. See Transactions of the Swedish Academy,
vol. iii. p. 285. It is most probable that the toad, when very
young, had got into a small cleft of the stone, where it nourished
itself with moisture and the insects which crept into it ; that the
cleft was at length closed up by sparry matter, and that the ani-
mal, by the time it grew. up, was thus completely incrusted. -

and causes of death are thereby rendered harmless ;
and whole parts which have been lost are again renewed.
To this belongs that phenomenon of the skin which we
find among most animals of this class. Snakes, frogs,
lizards, etc., cast their skin every year ; and it appears
that this method of becoming again young, contributes
very much to their support and duration. Something
of the like kind seems to prevail throughout the whole
animal world : birds change their feathers as well as
their bills, which is called moulting ; insects transform
themselves, and most quadrupeds change their hair and
their claws.

The tortoise and crocodile attain to the highest age,
as far as we have yet been able to learn from ob-
servation.

The tortoise, an indolent, slow in all its motions, and
phlegmatic animal, and which is so long in growing
that in twenty years one can scarcely observe an in-
crease of a few inches, lives to the age of a hundred
years and more.

The crocodile, a large, strong, vigorous animal, in-
closed in a hard coat of mail, incredibly voracious, and
endowed with extraordinary powers of digestion, lives
also very long ; and, according to the affirmation of
several travellers, is the only animal which grows as
long as it exists.

It is astonishing what instances of great age may be
found among fishes, the cold-blooded inhabitants of the
waters. We know from the ancient Roman history,
that in the imperial fishponds there were several lam-
preys (murcence) which had attained to their sixtieth
year ; and which had, at length, become so well ac

quainted and familiar with man that Crassus orator
unam ex illis defleverit*

The pike, a dry, exceedingly voracious animal, and
carp also, according to undeniable testimony, prolong
their life to a hundred and fifty years. The salmon
grows rapidly, *and dies soon. On the other hand, the
perch, the growth of which is slower, preserves its ex-
istence longer.

It appears here worthy of being remarked, that nat-
ural death occurs more rarely among fishes than in any
other part of the animal kingdom. The law of the
transition of one into another, according to the right of
the strongest, prevails here far more generally. One
devours another, the stronger the weaker; and one may
assert that death exists less in the water, as the dying
pass immediately into the substance of another living
being, and consequently the intermediate state of death
is less common than on land. Putrefaction takes place
in the stomach of the stronger. This regulation is a
proof of exalted and divine wisdom. If the innume-
rable millions of the inhabitants of the waters which die
daily, remained only one day unentombed, or, what is
the same thing, not devoured, they would speedily dif-
fuse abroad the most dreadful pestilential evaporation*
In water, where vegetation, that great means of correct-
ing animal putrefaction, exists in less extent, every
cause of corruption must be guarded against ; and on
this account continual life must prevail.

Among birds, also, there are several species which
live a long time ; and to this, without doubt, the follow-
ing circumstances contribute :

* That Crassus the orator shed tears for one of them when it
died.

DURATION OF LIFE IN BIRDS. 63

Irst. Birds are remarkably well clothed ; for no cov-
ering can be more perfect or better calculated to pre-
serve warmth than feathers.

2nd. They have, every year, a kind of reproduction,
or renovation, which is called moulting. During that
period, the bird appears to be somewhat sick ; casts, at
length, its old feathers, and acquires new ones. Many
cast their bills also ; an important part of renovation,
as they are thereby put in a condition to feed them-
selves much better.

3rd. Birds enjoy the purest air, and in the greatest
quantity.

4th. They are exposed to much motion ; but their
motion is the most healthful of all, as it consists of
both active and passive, that is to say, they are sus-
pended, and exert themselves only in moving forwards.

The golden eagle, a large strong animal with solid
vessels, attains to a very great age. There have been
instances of many living in menageries above a hundred
years.

The same is the case with the vulture and falcon,
both carnivorous animals. A gentleman at London, a
few years ago, received from the Cape of Good Hope
one that had been caught with a golden collar, on which
was inscribed in English, " His Majesty K. James of
England, An. 1610." It had, therefore, been at liberty
one hundred and eighty-two years from the time of its
escape. How old was it when it escaped ? It was of
the largest species of these birds, and possessed still no
little strength and spirit ; but it was remarked that its
eyes were blind and dim, and that the feathers of its
neck had become white.

64 ART OF PROLONGING LIFE.

The crow, a carnivorous bird with hard black flesh,
can extend its life also to a hundred years ; as can
likewise the swan, an animal exceedingly well feath-
ered, which feeds upon fish, and is fond of running
water.

The parrot, in this respect, distinguishes itself in a
particular manner. One has had instances of its liv-
ing sixty years a prisoner with man ; and how old
may it not have been when it was caught ? It is an
animal which eats and' digests almost all kinds of food,
which changes its bill, and which has hard, dark-colored
flesh.

The peacock lives to the twentieth year. On the
other hand, the cock, a hot, quarrelsome animal, does
not exist nearly so long. Of a still shorter life is the
sparrow. Small birds also live in general shorter. The
blackbird and goldfinch live, at most, only to the twen-
tieth year.

If we now turn our view towards the most perfect
animals, the mammalia, those which approach nearest to
man, we shall find amongst these also a very striking
difference of age.

That which attains to the greatest is perhaps the
elephant ; which, by its size, slow growth (for it grows
to the thirtieth year), exceedingly hard skin and teeth,
has the justest claim to longevity.

The age of the lion cannot be accurately determined;
but we have reason to think that it is of considera-
ble extent ; because some have been found without any
teeth.

The bear, though a great sleeper, and remarkably
phlegmatic when awake, has, however, no great dura-

tion of existence. A poor comfort for those who im-
agine that they have found in indolence the secret for
prolonging life.

The camel, on the other hand, a meagre, dry, active,
exceedingly hardy animal, becomes old. It generally
attains to the age of fifty, and sometimes of a hundred
years.

The horse does not live more than about forty years^
lie is a large, strong animal, but not well covered with
hair ; he is therefore of greater sensibility. He may,
however, ascribe his short life, in some measure, to
the severity of man ; for we do not yet know, by ex-
perience, how long he can live in a state of nature.
The life of the ass has about the same duration. The
mule, a production of both, is stronger lived, and be-
comes older.

What has been said respecting the great age of the
stag is a fable. It lives thirty years, and perhaps a lit-
tle over.

The bull, large and strong as he is, lives only a short
period about fifteen years, or at most twenty. Most
of the smaller animals, such as sheep, goats, the fox, the
hare, etc., live no more than seven or ten years ; except
dogs and swine, which can reach the age of fifteen or
twenty.

From this variety of observations the following result
may be drawn :

The animal world have far more external and inter-
nal movement, a more perfect and a more compounded
intensive life, and, without doubt, more self-consumption
than the vegetable. Besides, the organs of this king-
5

66 ART OF PROLONGING LIFE.

dom are much tenderer, more complex, and more highly
finished. Animals, therefore, must have a shorter life
than plants. But for this reason they possess a greater
abundance of the vital power ; have more points of con-
tact with the whole of Nature that surrounds them, and
consequently more accession and restoration from with-
out. It must nevertheless be difficult, in this class, to
attain to a remarkably great age ; but a short life, also,
will occur very rarely. And this is what we find from
observation ; a mean age of between five and forty
years is the most common.

The sooner an animal is formed, the more rapidly it
arrives at perfection ; but the sooner it will decline and
lose its existence. This seems to be one of the most
general laws of Nature, and is confirmed throughout all
classes. Only one must not confound expansion with
growth, and reckon by the latter ; for there are animals
which grow as long as they live, and to which growth
forms part of their nourishment : but this law must be
referred, in particular, to the two following periods :

1. To the time of the first expansion in the egg,
either in or out of the body.

2. To the period of maturity, which one may consider
as the utmost boundary of physical conformation, and
as a proof that the being has now attained the highest
degree of finishing which it was physically capable of
receiving.

The rule, therefore, must be thus expressed : the less
time an animal requires for its formation in th e mother's
womb, or the egg, the sooner it will perish. The ele-
phant, which goes with young till the third year, live]

MATURITY OF ANIMALS. 67

also longest ; but the hind, the cow, the dog, which go
with young only from two to nine months, have a much
shorter existence. Quod cito fit, cito peril.*

Another law of great importance must also not be
omitted ; the sooner a being attains maturity, the sooner
it propagates ; but "the shorter will be the time of its
duration. This law, which we find so perfectly con-
firmed in the vegetable kingdom, prevails likewise,
without exception, in the animal. The greatest in-
stance of it is afforded by insects. Their first period
towards maturity, that is, their state as larva?, may con-
tinue very long, even several years ; but as soon as they
have undergone their grand transformation, that is, have
attained maturity, their existence is completely ended.
And among quadrupeds, it is certain that we may de-
termine the life of an animal with considerable pre-
cision, if we consider the epoch of maturity as the fifth
part of the whole duration of its existence.

The horse, ass, and bull, are at maturity in the third
or fourth year, and live from fifteen years to twenty.
Sheep come to maturity the second year, and live from
eight to ten years.

All horned animals, in general, live shorter than
those which have not horns.

Animals with dark-colored black flesh, are, on the
whole, longer-lived than those which have white flesh.

And all quiet, timid animals, have a shorter existence
than those of a contrary temperament.

A certain covering of the body seems, in a particular
manner, to have a great influence on the duration of
life. Thus birds, which undoubtedly have the best and
* That which is quickly formed, quickly perishes.

68 ART OF PROLONGING LIFE.

most durable covering, live exceedingly long ; as do also
the elephant, the rhinoceros, and the crocodile, which
have the strongest skin.

The nature of their motion has its influence also.
Running seems to be the least favorable to duration of
life; while, on the other hand, swimming, flying, and,
in short, that motion which is compounded of the active
and the passive, seems to be the most favorable.

This principle, therefore, is confirmed : the more in-
tensive the life of a being is, and the less its internal
consumption, that is to say, according to the common
mode of expression, the more imperfect the life of a
being is, it will be so much the more lasting. On the
other hand, the tenderer, finer, and more complex the
organization, and the more perfect the life is, it will be
of so much the less duration.

This is shown in the clearest manner, by the follow-
ing observations :

1st. Zoophytes, or plant animals, whose whole organ-
ization consists in a mouth, a stomach, and a straight
gut, have a life exceedingly tenacious and difficult to be
destroyed.

2nd. All cold-blooded animals have, in general, a
stronger and longer life than the warm-blooded ; or,
what amounts to the same thing, those which do not
breathe have in this an advantage over those which
breathe. And for what reason ? Breathing is the
source of internal heat, and accelerates consumption.
An animal which breathes has, as it were, a double cir-
culation, the common and the less through the lungs ;
besides a double surface, which comes into continual
contact with the atmosphere, the skin, and the superfices

RESTORATIVE POWERS OF ANIMALS. 69

of the lungs ; lastly, a far stronger irritability, and con-
sequently a much greater self-consumption both inter-
nally and externally.

3rd. Animals which inhabit the water live longer, in
general, than those that reside in the air ; and for this
reason, because an animal in water evaporates very
little, and because water does not consume nearly so
much as the atmosphere.

4th. Lastly, the strongest proof what an astonishing
effect lessening the external consumption has in the
prolongation of life, is afforded by instances where that
consumption has been rendered totally impossible. I
mean those of toads inclosed in blocks of stone, where,
by the external consumption being suspended, they pre-
served their life so much the longer. In that s'ate
nothing could evaporate, nothing could be dissolved ;
for the small quantity of air which was perhaps shut
up with them, must have soon become so much satu-
rated as to be incapable of receiving any thing more.
On this account the animal could exist so long without
nourishment ; for the need of nourishment arises from
the loss which we sustain by evaporation and consump-
tion. In such a state, where every thing remains as it
was, no reparation is required. By such means the
vital power and organization might be retained per-
haps a hundred times longer than in the natural con-
dition.

The last principle on which the duration of life is
founded, more perfect restoration, is fully confirmed
likewise in this kingdom of Nature.

The highest degree of restoration is the reproduction
of entirely new organs.

70 ART OF PROLONGING LIFE.

This power is found, in a wonderful degree, in the
class of plant-animals, worms, and amphibia, in short
of those animals which have cold blood and no bones,
or only such as are cartilaginous. And amongst all
these animals there exists a most remarkable duration
of life.

Somewhat of the same nature is the casting of scales
among fishes; of the skin among snakes, crocodiles,
frogs, etc. : of the feathers and bill among birds : and
we always observe, that the more perfect this renova-
tion is, the duration of life is proportionably longer.

A highly important circumstance, however, in regard
to restoration, is nourishment ; and here a most essen-
tial difference is manifested between the vegetable and
animal world. All plants derive their nourishment
from without : on the other hand, it is an invariable law
of Nature, among animals, that the nourishment must
first pass into a cavity or bag, commonly called the
stomach, destined for that purpose, before it can be re-
ceived into the mass of the juices and become a part of
the animal ; and the imperfect polype, as well as the
elephant, has these characteristics of the animal, a
mouth, and a stomach.

It is this which forms the grand basis of the animal
world ; the characterizing difference between animals
and plants ; and upon which is originally grounded the
superior advantage of individuality ; of internal, more
perfect, and more expanded life. Among animals, the
substance which is received may obtain a far higher
degree of preparation than among plants ; the roots
(the lacteal vessels) are, as it were, within ; and receive
the nourishing juices, already assimilated and purified,

RESTORATIVE POWERS OF ANIMALS. 71

through the intestines. Animals, therefore, are subject
to more secretions and excretions than plants ; and, for
the same reason, the course of the nourishing juices
and of all movements proceeds, among animals, from
the internal to the external part, and among plants from
the external to the internal. For this reason, also, the
progress of death, in an animal, is from the external to
the internal parts : in a plant the case is reversed ; and
one may often see trees without pith or internal sub-
stance, of which nothing exists but the bark, and which,
however, still continue to live. For the above reason,
likewise, animals can receive nourishment far more
various, and restore themselves in a much more perfect
manner, and, by these means, counterbalance the
stronger self-consumption.

LET us now proceed to the grand source of our
information, the history of man ; and let me there col-
lect examples which will be of utility in the present
research.

I shall, therefore, lay before my readers the most
remarkable instances of the greatest age among man-
kind ; and we shall thence see in what climate, under
what favorable circumstances, in what condition, and
what state both of mind and body man has attained to
the highest degree of longevity : an agreeable review,
which will make known to us a peculiar part of the
history of the world, the history of the age of man, and
the venerable gallery of the Nestors of ancient periods
and nations. I shall occasionally add a few short char-
acteristics, to give at the same time a hint how far
character and temperament have an influence on the
duration of life.

DURATION OF HUMAN LIFE. 73

It is commonly believed that, during the early peri-
ods of the world, the lives of its inhabitants were more
youthful and more perfect ; that these primitive men
had a gigantic size, incredible strength, and a most
astonishing duration of life. A variety of such notions
were long prevalent among mankind ; and to these we
are indebted for the origin of many romantic tales.
Some have not hesitated seriously to ascribe to our
forefather Adam, the height of nine hundred yards, and
the age of almost a thousand years. But the accurate
and rational investigation of modern philosophy has
converted the supposed bones of giants, found in differ-
ent parts of the earth, into those of the elephant and
rhinoceros; and acute theologists have shown that the
chronology of the early ages was not the same as that
used at present. Some, particularly Hensler, have
proved, with the highest probability, that the year till
the time of Abraham consisted only of three months ;
that it was afterwards extended to eight ; and that it
was not till the time of Joseph that it was made to con-
sist of twelve. These assertions are, in a certain de-
gree, confirmed by some of the eastern nations, who still
reckon only three months to the year ; and besides, it
would be altogether inexplicable why the life of man
should have been shortened one half immediately after
the flood. It would be equally inexplicable why the
patriarchs did not marry till their sixtieth, seventieth,
and even hundredth year; but this difficulty vanishes
when we reckon these ages according to the before-
mentioned standard, which will give the twentieth or
thirtieth year ; and consequently, the same periods at
which people marry at present. The whole, therefore,

74 ART OF PROLONGING LIFE.

according to this explanation, assumes a different ap-
pearance. The sixteen hundred years before the flood
will become four hundred and fourteen ; and the nine
hundred years (the highest recorded) which Methuselah
lived, will be reduced to two hundred, an age which
is not impossible, and to which some men in modern
times have nearly approached.

In profane history, also, we have an account of many
heroes and Arcadian kings of those periods who attained
to the age of several hundred years ; but these pre-
tended instances of longevity can be explained in the
same manner.

With the period of Abraham, a period when history
seems first to be established on more certain grounds,
we find mention of a duration of life which can be still
attained, and which no longer appears extraordinary,
especially when we consider the temperate manner in
which the patriarchs lived; and that, as they were
nomades, or a wandering people, they were much ex-
posed to the free open air.

From the history of the Jews we are enabled to col-
lect the following facts. Abraham, a man of great and
resolute mind, who was fortunate in all his undertakings,
attained to the age of 175 years ; his son Isaac, a chaste,
peaceable man, and fond of tranquillity, to 180 ; Jacob,
who was also a lover of peace, but crafty and cunning,
lived only 147; Ishmael, a warrior, 137; Sarah, the
only female of the ancient world with whose duration of
life we are acquainted, lived 127 years; Joseph, a man
of great prudence and political talents, much afflicted in
his youth, but greatly honored in his latter days, lived
to the age of 110.

EXAMPLES OF GREAT AGE. 75

Moses, a man of extraordinary strength and spirit,
rich in deeds but weak in words, carried his life, during
which he was exposed to great care and fatigue, to the
age of 120. But he even complains that the life of man
endures only threescore and ten, or at most fourscore
years ; and we hence find that, in regard to age, the
case was exactly the same three thousand years ago as
it is at present.

The warlike and ever active Joshua lived to the age
of 110. Eli, the high-priest, a corpulent, phlegmatic
man, of a resigned disposition, lived to be only 90 ; but
Elisha, severe towards others and towards himself, who
despised convenience and riches, lived far above 100.
In the latter period of the Jewish State, the prophet
Simeon, a man full of hope and confidence in God, was
distinguished by a li e of 90 years.

However replete with fables the history of the Egyp-
tians may be, the age of their kings, recorded from the
earliest periods, presents nothing remarkable. The
longest reign is somewhat above fifty years.

If we judge according to the account of Lucian, we
must form a very high idea of the great age of the
Seres, or the ancient Chinese. They are expressly call-
ed Macrobii ; and Lucian ascribes their longevity to their
drinking water in great abundance. Is it not probable
that they may, even then, have been acquainted with
tea?

Among the Greeks we find several instances of great
age. The wise Solon, a man of much magnanimity,
depth of thought and ardent patriotism, though not in-
different in regard to the enjoyments of life, attained
the age of 80.

76 ART OF PROLONGING LIFE.

Epiraenides of Crete is said to have lived 157 years.
The poet Anacreon, so fond of mirth and jollity, lived
to the age of 80 ; as did also Sophocles and Pindar.
Georgias of Leontium, a great orator, a man who had
travelled much, and who spent a great deal of his time
in the company of young people and in giving them in-
.struction, prolonged his life to the age of 108 years.
Protagoras of Abdera, an orator and traveller also,
lived 90 ; and Isocrates, a man of great temperance and
modesty, lived 98. Democritus, the friend and searcher
of Nature, a man also of a good temper and serene
mind, lived 109 years ; and the frugal, but slovenly
Diogenes, 90. Zeno, the founder of the Stoical sect,
and a master in the art of self-denial, attained nearly
to the age of 100 years ; and Plato, one of the most di-
vine geniuses that ever existed, and a friend to rest and
calm meditation, to that of 81. Pythagoras, who in
his doctrine recommended good regimen, moderation of
the passions, and the gymnastic exercises, became also
very old. He used to divide the life of man into four
equal parts. From the first to the twentieth year he
called him a child, a man begun ; from the twentieth to
the fortieth, a young man ; from the fortieth to the six-
tieth, a man ; from the sixtieth to the eightieth, an old
or declining man ; and after this period he reckoned
him no more among the living, let him live to whatever
age he might.

Among the Romans the following instances deserve
to be remarked :

M. Valerius Corvinus, a man of great boldness and
courage, extremely popular, and always fortunate, was
above the age of 100. Orbilius, the celebrated Orbil-

EXAMPLES OF GREAT AGE. 77

ius, first a soldier and then a pedagogue, but who always
exercised military severity, attained, in this kind of life,
to the age of above 100 years. How far Hermippus,
the instructor of young maids, carried his life, we have
seen before. Fabius, well known on account of his de-
lay, showed, by an age of 90 years, that something may
be gained even from death by the same means. And
Cato, that man with an iron body and iron mind, fond
of a country life, and an enemy to physicians, lived to
the age of above 90.

We have likewise remarkable instances of the lon-
gevity of Roman ladies. Terentia, the wife of Cicero,
notwithstanding her many misfortunes, cares, and the
gout, with which she was tormented, lived to the age of
103. And Livia, the wife of Augustus, an imperious,
passionate, but fortunate woman, attained to that of 90.

It is particularly worthy of remark, that several in-
stances occur of Roman actresses who became old ; an
advantage which they have now unfortunately lost, and
which seems to show that more vital consumption is
connected with their occupation at present than former-
ly. One Luceja, who came on the stage very young,
performed a whole century, and even made her appear-
ance publicly when in her 112th year. Galeria Copi-
ola, an actress, and dancer also, w r as 90 years old when
she first performed in the theatre ; and she was again
brought forward as a wonder, in order to compliment
Pompey. But this even was not the last time of her
acting ; for she appeared once more, to show her re-
spect for Augustus.

A very valuable collection in regard to the duration
of life in the time of the emperor Vespasian, has been

78 ART OF PROLONGING LIFE.

preserved to us by Pliny, from the records of the Cen-
sus, a source perfectly sure and worthy of credit. It
there appears, that in the year when that numbering of
the people took place, the seventy-sixth of our era,
there were living in that part of Italy which lies be-
tween the Apennines and the Po, only 124 men who
had attained the age of 100 years and upwards, name-
ly, fifty-four of 100, fifty-seven of 110, two of 125, four
of 130, four of from 135 to 137, and three of 140. Be-
sides these, there were in Parma five men, three of
whom were 120, and two 130 ; in Placentia, one of 130 ;
at Faventia, a woman of 132 ; and in Vellejacium, a
small town near Placentia, there lived ten persons, six
of whom had attained to the age of 110, and four to
that of 120.

The bills of mortality also of the celebrated Ulpian
agree in a most striking manner with ours, and in par-
ticular with those of great cities. From these it appears
that one might with great propriety compare Rome to
London, in regard to the probability of the duration of
life.

We have sufficient reason, therefore, to believe that
the duration of life in the time of Moses, the Greeks,
and the Romans, was invariably the same as at present ;
and that the age of the earth has no influence on the
longevity of its inhabitants, that difference excepted
which may be produced by the cultivation of its sur-
face, and the difference of climate that may thence
arise.

Thus, for example, it is certain that in Italy, at pre-
sent, neither so many nor so old people are to be found
as in the time of Vespasian ; but the reason is, that the

LONGEVITY OF SOVEREIGNS. 79

climate then, on account of the woods and forests, was
much colder,* and rendered the men more robust. It
is also not improbable that the natural warmth of the
earth itself may alter, and be accumulated sometimes in
one region and diminished in another.

The result of this research will therefore be, that man
can still attain to the same age as ever. The difference
only is, that more attained to old age formerly than at
present.

Let us now take a view of the different states and
conditions of men, ^n4, in this respect, turn our eyes in
particular to modern times.

To begin with emperors, kings, and, in short, the
great ones of the earth : has Nature, which has con-
ferred upon them, in the highest degree, all the advan-
tages and enjoyments of this world, bestowed upon them
also her best gift, a longer duration of life ? Unfortu-
nately not. Neither ancient nor modern history informs
us that this prerogative belongs exclusively to them.
In ancient history we find only a few kings w r ho attained
to their eightieth year ; and this is equally the case in
the modern. In the whole catalogue of Roman and
German emperors, reckoning from Augustus to the pres-
ent time, which includes altogether above two hundred,
we find, (the two first, Augustus and Tiberius, except-
ed) only four who arrived at the age of 80 ; namely,
Gordian, Valerian, Anastasius, and Justinian.

Augustus, a man of a peaceful, moderate disposition,
though quick and lively in action, temperate in the en-

* Of this we have several instances. Pliny, for example,
speaks of winters when the wine was congealed in the cellars,
and the Tyber frozen to the bottom.

80 ART OF PROLONGING LIFE.

joyments of the table, but more susceptible therefore of
the pleasure arising from the arts and the sciences, at-
tained to the age of seventy-six. He used none but the
simplest food ; ate only when he had an appetite ; never
drank above a pint of wine ; and considered mirth and
good company as the best seasoning of his meals. He
possessed a serene mind, was a great favorite of fortune,
and entertained such ideas respecting the term of life,
that he said to his friends a little before his death, Plau-
dite, amid ! " Applaud, my friends ; the farce is ended ! "
a disposition of mind exceedingly favorable to longev-
ity. In the thirtieth year of his age he was attacked
by so severe and dangerous a disease that his life was
despaired of. It was a sort of nervous disorder, which,
by the warmth and hot baths recommended to him by
his ordinary physicians, must have been rendered still
worse. Antonius Musa resolved to treat his case in a
manner totally different. He obliged him to keep him-
self perfectly cool, and to use the cold bath ; and by
these 1 means his health was again soon restored. This
disorder, as well as the useful change which it effected
in his mode of living, contributed very much, in all pro-
bability, to the prolongation of his life.

From this account we learn also, that the method by
the cold bath is improperly called the English method,
since it appears to be of so great antiquity.

The emperor Tiberius lived two years longer. He
was of a violent temper, but vir lentis maxillis,* as Au-
gustus called him ; a friend to voluptuousness, though

* Literally : "A man of slow jaws," which may mean that he
masticated slowly, as well as that he was moderate in the quan-
tity of his food. EDITOR.

LONGEVITY OF SOVEREIGNS. 81

still attached to regimen, and, even amidst enjoyment,
not inattentive to his health ; so that he used to say he
considered a man as a fool, who, after the thirtieth year
of his age, consulted physicians respecting diet ; because
every one, with the least attention, must before that pe-
riod have discovered what was useful and what preju-
dicial to him.

Aurengzeb, that celebrated conqueror, attained to the
age of 100 ; but he is not to be considered so much a*
king as a nomade or wanderer.

Great age is equally uncommon in the royal and]
princely families of modern times. We must, however,
except the kings of France, of the house of Bourbon,
two of whom, who succeeded each other, attained the
age of 70.

Frederic IL, that great prince, one of the most im-
portant instances in modern times, must not be here
omitted. He was great in every thing, even in what
related to his medicine. Pie not only attained to an age
very rare among kings that of 7C, but, what is still
of greater weight, attained to it amidst a life more ex-
posed to care, labor, and fatigue, than that perhaps of
any other man who ever existed, as he spent twenty
years of it in active war, during which he submitted to
all the toils of a common soldier ; but with this differ-
ence, that, as commander-in-chief he thought for all, and
frequently passed the night, while others were enjoying
repose, in the deepest meditation, and in forming new
plans for his future operations.

The ecclesiastical princes, in this respect, -have not
been more fortunate. Of three hundred popes, who
may be reckoned up, no more than five attained to or

exceeded the age of eighty, though they possessed the
advantage of obtaining the pontifical chair at a late pe-
riod, and had therefore a greater probability of enjoy-
ing longevity.

An extraordinary number of instances, however, may
be found among the hermits and monks, who, with the
strictest regimen, self-denial, and abstraction, while they
divested themselves of all human passions, and avoided
such intercourse as might tend to excite them, led a life
of contemplation, but united with bodily exercise and the
enjoyment of free air. Thus the apostle John attained
to the age of 93 ; Paul the hermit, by means of an al-
most incredibly severe regimen in a grotto, to that of
113 ; and St. Anthony to that of 105. Athanasius and
Jerome also exceeded the age of 80.* In modern times,
since mental abstraction, self-denial, and temperance
have undergone some variations, instances of this kind
are become more uncommon.

Deep-thinking philosophers have at alj times been
distinguished by their great age, especially when their
philosophy was occupied in the study of Nature, and
afforded them the divine pleasure of discovering new
and important truths : the purest enjoyment, a benefi-
cial exaltation of ourselves, and a kind of restoration
which may be ranked among the principal means of
prolonging the life of a perfect being. The most an-
cient instances are to be found among the Stoics and
the Pythagoreans, according to whose ideas subduing the
passions and sensibility, with the observation of strict

Canterbury, to that of 88 ; and Wilfred, Bishop of Hexham,
through a turbulent career, to 76. EDITOR.

LONGEVITY OF PHILOSOPHERS. 83

regimen, were the most essential duties of a philosopher.
We have already considered the example of a Plato and
an Isocrates. Apollonius of Tyana, an accomplished
man, endowed with extraordinary powers both of body
and mind, who, by the Christians, was considered as a
magician, and by the Greeks and Romans as a messen-
ger of the gods, in his regimen a follower of Pythago-
ras, and a friend to travelling, was above 100 years of
age. Xenophilus, a Pythagorean also, lived 106 years.
The philosopher Demonax, a man of the most severe
manners and uncommon stoical apathy, lived likewise
100. Being asked, a little before his death, how he
wished to be buried, he replied, " Give yourself no con-
cern on that point ; the smell will soon bury the car-
cass." " But," returned his friends, " do you wish, then,
to become food to the dogs and the birds?" '"Why
not ? " replied he ; " during my whole life I have en-
deavored as much as I could to be serviceable to man,
why should I not, after my death, be of some use also
to animals?"

Even in modern times philosophers seem to have ob-
tained this preeminence, and the deepest thinkers
appear in that respect to have enjoyed, in a higher de-
gree, the fruits of their mental tranquillity. Kepler
and Bacon both attained to a great age ; and Newton,
who found all his happiness and pleasure in the higher
spheres, attained to the age of 84.* Euler, a man of in-
credible industry, whose works on the most abstruse
subjects amount to above three hundred, approached

* Kepler only reached the age of 59 ; Bacon attained that of

near to the same age ; and Kant, the first philosopher
now alive, still shows that philosophy not only can pre-
serve life, but that it is the most faithful companion of
the greatest age, and an inexhaustible source of happi-
ness to one's self and to others.*

Academicians, in this respect, have been particularly
distinguished. I need mention only the venerable Fon-
tenelle, who wanted but one year of a hundred, and that
Nestor, Formey, both perpetual secretaries, the former
of the French, and the latter of the Berlin Academy.

We find, also, many instances of long life among
schoolmasters; so that one might almost believe that
continual intercourse with youth may contribute some-
thing towards our renovation and support.

But poets and artists, in short all those fortunate mor-
tals whose principal occupation leads them to be con-
versant with the sports of fancy and self-created worlds,
and whose whole life, in the properest sense, is an
agreeable dream, have a particular claim to a place in
the history of longevity. We have already seen to
what a great age Anacreon, Sophocles, and Pindar at-
tained. Young, Voltaire, Bodmer, Haller, Metastasio,
Gleim, Utz, and Oeser, all lived to be very old ;f and

I here flatter myself with the hope, and I shall no
doubt be joined in my wish by every one of my readers,
that Wieland, the prince of the German poets, may af-
ford the newest confirmation of this position.*

The most extraordinary instances of longevity are to
be found, however, only among those classes of .man-
kind who, amidst bodily labor, and in the open air, lead
a simple life agreeable to nature, such as farmers, gar-
deners, hunters, soldiers, and sailors. In these situa-
tions man still attains to the age of 140, and even 150.
I cannot here deny myself the pleasure of giving a
more particular account of some of these instances ; for,
in cases of this kind, the most trifling circumstance is
often interesting, and may be of importance.

86 ART OF PROLONGING LIFE.

In the year 1670 died Henry Jenkins, of Yorkshire.
He remembered the battle of Floddenfield in 1513, and
at that time he was twelve years of age. It was
proved, from the registers of the Chancery and other
Courts, that he had appeared, 140 years before his
death, as an evidence, and had an oath administered to
him. At the time of his death, he was, therefore, 169
years old. His last occupation was fishing; and when
above the age of 100, he was able to swim across rapid
rivers.

Next to him, in point of age, is another Englishman,
Thomas Parr, of Shropshire. He was a poor farmer's
servant, and obliged to maintain himself by daily labor.
When above 120 years of age, he married a widow for
his second wife, who lived with him twelve years, and
who asserted that during that time he never betrayed
any signs of infirmity or age. Till his 130th year he
performed all his usual work, and was accustomed even
to thresh. Some years before his death, his eyes and
memory began to fail ; but his hearing and senses con-
tinued sound to the last. In his 152nd year his fame
had reached London ; and as the king was desirous of
seeing so great a rarity, he was induced to undertake a
journey thither. This, in all probability, shortened his
existence, which he otherwise might have preserved
some years longer ; for he was treated at Court in so
royal a manner, and his mode of living was so totally
changed, that he died soon after, at London, in 1635.
He was 152 years and nine months old, and had lived
under nine kings of England. What was most remark-
able in regard to this man is, that when his body was
opened by Dr. Harvey, his internal organs were found

INSTANCES OF LONGEVITY. 87

to be in the most perfect state, nor was the least symp-
tom of decay to be discovered in them. His cartilages
even were not ossified, as is the case in all old people.
The smallest cause of death had not yet settled in his
body ; and he died merely of a plethora, because he had
been too well treated.

This Parr is a proof that, in many families, a consti-
tution so favorable to longevity may transmit a remark-
ably good stamen vitce. His great grandson died at
Cork, a few years ago, at the age of 103.

The following instance is almost of the same kind :
A Dane, named Draakenberg, born in 1626, served as a
seaman in the Royal Navy till the ninety -first year of
his age, and spent fifteen years of his life as a slave in
Turkey, and in the greatest misery. When he was 111,
and had settled to enjoy tranquillity, he resolved to
marry, and united himself to a woman of threescore.
He, however, outlived her a long time ; and in his
130th year, fell in love with a young country girl, who,
as may be well supposed, rejected his proposal. He
then tried his fortune with several others, but as he had
no better success, he at length resolved to continue
single, and in that condition lived sixteen years. He
died in the year 1772, in the 146th year of his age.
He was a man of a rather violent temper, and exhibited
frequent proofs of his strength during the last years of
his life.

In the year 1757, J. Emngham died in Cornwall, in
the 144th year of his age. He was born of poor pa-
rents in the reign of James I., and had been brought up
to labor from his infancy. He had served long as a
soldier and corporal ; and had been present at the bat<~

tie of Hochstedt. He at length returned to the place
of his nativity, and worked as a day-laborer till his
death. It is to be remarked, that in his youth he never
drank strong, heating liquors ; that he always lived re-
markable temperately, and seldom ate flesh. Till his
100th year he scarcely knew what sickness was ; and
eight days before his end, he had walked three miles.

In the year 1792, died, in the Duchy of Holstein, an
industrious day-laborer, named Stender, in the 103rd
year of his age. His food, for the most part, was noth-
ing but oatmeal and buttermilk. He rarely ate flesh ;
and what he used was always much salted. He scarcely
ever had thirst, and therefore drank very seldom. He
was fond of smoking tobacco. In his old age he first
began to drink tea, and sometimes coffee. He lost his
teeth early. He was never sick ; and could not be out
of humor ; that is to say, it was physically impossible
that his bile should ever overflow. He avoided with
great care every cause of strife or contention. He
had the greatest trust in Providence ; and this was his
consolation and support in all his misfortunes and
troubles. His chief dependence always was in the
goodness of God.

One of the most singular instances that, amidst the
ficklest sports of fortune, continual danger, and the
most destructive influences, the life of man may be pre-
served to an incredible length, is the following : An
old soldier, named Mittelstedt, died in Prussia, in the
year 1792, in the 112th year of his age. This man
was born at Fissahn, in that country, in the month of
June, 1681 ; and was lost at the gaming-table by his
master, who in one evening staked his whole equipage

INSTANCES OF LONGEVITY. 89

and six more servants. He then entered into the army,
and served as a soldier sixty-seven years. He was
present in all the campaigns under Frederick I., Fred-
erick William L, and Frederick II., and, in particular,
in those of the seven years' war ; and had been engaged
in seventeen general actions, in which he braved num-
berless dangers and received many wounds. In the
seven years' war his horse was shot under him, and he
was then taken prisoner by the Russians. After sup-
porting all these difficulties, he married ; and having
lost two wives successively, he married a third, in
1790, when he w r as in the 110th year of his age. A
little before his death he was still able to walk two
miles, every month, in order to receive his small pension.

The same year died at Neus, in the Archbishopric
of Cologne, H. Kauper, a veteran of 112. He wns
a man of a strong make; had been accustomed to
walk a little every day ; could read till his death with-
out spectacles, and retained the use of his senses to the
last.

Helen Gray died a few years ago, in the 105th year
of her age. She was of small stature, exceedingly
lively, peaceable, and good-tempered, and a few years
before her death acquired new teeth.

Thomas Garrick was alive last year, (1795,) in the
county of Fife, in the 108th year of his age. He still
possessed great vigor ; and was celebrated, as he always
had been, on account of his extraordinary appetite. For
twenty years he had never been confined to his bed by
sickness.

Not long ago there was still alive at Tacony, near
Philadelphia, a shoemaker named R. Glen, in the 114th

90 ART OF PROLONGING LIFE.

year of his age. He was by birth a Scotchman, had
seen King William III., enjoyed the perfect use of his
sight and memory, ate and drank with a keen appetite,
had a good digestion, labored the whole week, and on
Sunday walked to hear divine service in the church
at Philadelphia. His third wife was still alive ; she
was thirty years of age, and lived happily with her
husband.

A certain baron, Baravicino de Capellis, died in 1770,
at Meran, in Tyrol, at the age of 104. He had been
married to four wives : the first he married in his four-
teenth, and the last in his eighty-fourth year. By his
fourth wife he had seven children, and when he died
she was pregnant with the eighth. The vigor of his
body and mind did not forsake him till the last months
of his life. He never used spectacles, and when at a
great age would frequently walk a couple of miles.
His usual food was eggs ; he never tasted boiled flesh;
sometimes he ate a little roasted, but always in very
small quantity : and he drank abundance of tea with
rosa-solis* and sugar-candy.

Anthony Senish, a farmer of the village of Puy, in
Limoges, died in 1770, in the lllth year of his age.
He labored till within fourteen days of his death;
had still his teeth and his hair; and his sight had
not failed him. His usual food was chestnuts and
Turkish corn. He had never been bled, nor used any
medicine.

These are all the instances of great age in modern
times with which I am 'acquainted. Persons of 100
years I omit, for these are more common. A carpenter

died a few years ago at Btirgel, near this place, in his
104th year. He worked daily till his death ; and his
favorite employment, at last, was spinning yarn. One
day, as he was sitting at his wheel, his daughter ob-
served it motionless ; she immediately went up to him,
and found him dead.

Physicians, who so abundantly dispense to others the
means of health and life, ought to claim here a distin-
guished place. But unfortunately this is not the case.
It may be said of them, in general : Aliis inserviendo
consumuntur; aliis medendo moriuntur.*

At any rate, mortality is greater among practical
physicians than perhaps among men of any other pro-
fession. They have the least opportunity of observing
those prudential rules and precautions, for preserving
health, which they lay down to others ; and there are
few employments in which the powers both of the body
and mind are exposed to so much consumption as in
this. Head and feet must be always exercised in com-
mon. But the greatest mortality prevails during the
first ten years of their practice. A physician who has
fortunately withstood that period, attains to a certain
strength of constitution, a kind of insensibility to fatigue
and the causes of disease ; by custom, noxious effluvia
and the poison of infectious disorders becomes less pre-
judicial; and he acquires more indifference for the
heart-melting scenes of woe, and the numberless mise-
ries, the consequences of vice and moral evil, which his
business condemns him to be a daily spectator of: and

* In serving others they are consumed ; in healing others they
are destroyed. EDITOR.

thus a physician who has luckily passed his time of
probation, may become an old man ;

A striking instance of this is afforded by our prede-
cessor, Hippocrates, who lived to the age of 109. His
whole life was employed in the study of Nature, in
travelling, and in visiting the sick ; but he passed more
of his time in small villages and in the country than in
great cities. Galen, Crato, Forestus, Plater, Hoffman,
Haller, Van Swieten, and Boerhaave all attained to a
considerable age.*

In regard to shortness of life, miners, and those em-
ployed in melting-houses, are particularly distinguished,
as well as those who live under the earth, or are con-
tinually exposed to poisonous effluvia. In some mines,
which contain much arsenic and cobalt, the workmen
do not live to be older than thirty.

I shall now take a short view of the difference of
age, as arising from climate, or rather the nature of the
soil.

Sweden, Norway, Denmark, and England have, in

modern times, without doubt, produced the oldest men.*
Instances of some who attained to the age of 130, 140,
150, have occurred in these countries.

However favorable a northern climate may be to
longevity, too great a degree of cold is, on the other
hand, prejudicial to it. In Iceland, and the northern
parts of Asia, such as Siberia, men attain at most to the
age of sixty or seventy.

Besides England and Scotland, Ireland is celebrated
for the longevity of its inhabitants. In Dunsford, a
small place in that country, there were living, at one
time, eighty persons above the age of fourscore. And
Lord Bacon says there was not a village in the whole
island, as he believed, in which there was not one man
upwards of eighty.

In France, instances of longevity are not so abun-
dant ; though a man died there, in the year 1757, at the
age of 121.

The case is the same in Italy ; yet in the northern
province of Lombardy there have been some instances
of great age.

In Spain, also, there have been some instances, though
seldom, of men who lived to the age of 110.

That healthy and beautiful country, Greece, is still
as celebrated as it was formerly in regard to longevity.
Tournefort found, at Athens, an old consul who was

number a very small proportion, namely 72 (27 males, 45 females),
were returned from London; while 137 (43 males, 94 females),
were inhabitants of Wales. EDITOR.

118 years of age. The island Naxos is particularly
celebrated on this account.

Even in Egypt and India there are instances of
long life, particularly among the Bramins, Anchorites,
and Hermits, who detest the indolence and intemperance
of the other inhabitants of these countries.

Ethiopia formerly was much celebrated for its lon-
gevity ; but a contrary account is given of it by Bruce.

Some districts of Hungary are particularly distin-
guished by the great age of the people who reside in
them.

Germany contains abundance of old persons ; but
it affords few instances of very long life.

Even in Holland people may become old ; but this is
not often the case, and few live there to the age of a
hundred.

THAT 1 may not tire the patience of my readers by
too great a multitude of examples, I shall here stop, and,
in future, introduce them only occasionally, as the sub-
ject may require.

Let me be permitted, therefore, to collect the general
result of the observations above made, and to draw from
them the following important conclusions :

I. The age of the world hitherto has had no percep-
tible influence on that of man ; and people may still
become as old as in the time of Abraham, and even of
earlier epochs. There certainly have been periods
when men lived sometimes longer and sometimes short-
er ; but this evidently did not arise from the world, but
from man himself. When men were in a savage state,
simple, laborious children of Nature, and much exposed
to the open air, as shepherds, hunters, and farmers,
great age was very common among them ; but when

96 ART OF PROLONGING LIFE.

they began gradually to despise the dictates of Nature,
to study refinement, and to indulge in luxury, the dura-
tion of their life became shorter. The same people,
however, restored by a revolution to their former rude
state, and to manners more agreeable to Nature, can
again attain to their ancient longevity. These, conse-
quently, are unsettled periods, which only pass away
and return. Mankind, in general, do not suffer by them,
and retain that duration of life which is appointed for
them.

II. Man, as we have above seen, can, in almost all
climates, in the frigid or torrid zone, attain to a great
age. The only difference seems to be, that this is the
case in some much more than in others ; and that though
man can attain to a great age, people in general do not
attain to the greatest.

III. Even in districts where mortality in general is
very great, individuals may attain to a greater age than
in places where general mortality is less. I shall, by
way of example, mention the warm countries of the
East. There, mortality, upon the whole, is very small :
hence their extraordinary population ; and infancy, in
particular, suffers there much less on account of the con-
tinually uniform and pure temperature of the atmos-
phere. Yet a much smaller proportion of old people
are found in these countries than in the northern, where
mortality in general is greater.

IV. Places, the situation of which is high, have, in
general, more and purer air than those which stand
low ; though here, also, there is a certain limitation, and
the rule cannot be thus laid down : the higher the better.
The greatest degree of height, the glaciers, is, on the

INFLUENCE OF CLIMATE. 97

contrary, prejudicial to health ; and Switzerland, with-
out doubt the highest land in Europe, has produced
fewer instances of longevity than Scotland. For this
there are two reasons : First, the atmosphere at a great
height is too dry, ethereal, and pure, and consumes,
therefore, speedier. Secondly, the temperature of it is
too variable ; heat and cold succeed each other too rap-
idly ; and nothing is more unfavorable to duration of
life than very sudden changes.

V. In cold climates, men in general become older
than in warm ; and for two reasons : First, because, in.
warm countries vital consumption is greater ; and se-
condly, because, in cold countries, the climate, being
more temperate, checks vital consumption. This, how-
ever, is the case only in a certain degree. By the high-
est cold, such as that of Greenland, Nova Zembla, etc.,
the duration of life is shortened.

YI. Uniformity in the state of the atmosphere, parti-
cularly in regard to heat, cold, gravity, and lightness,
contributes, in a very considerable degree, to the dura-
tion of life. Countries, therefore, where sudden and
great variations in the barometer and thermometer are
usual, cannot be favorable to longevity. Such countries
may be healthy, and many men may become old i
them ; but they will not attain to a great age, for all
rapid variations are so many internal revolutions ; and
these occasion an astonishing consumption, both of the
powers and the organs. In this respect Germany is
particularly distinguished; for its situation renders it
subject to a continual mixture of heat and cold, of
northern and southern climate, where one often experi-
ences, in the course of the same day, both frost and the
7

98 ART OP PROLONGING LIFE.

utmost heat ; and where the month of March may be
extremely warm, and that of May accompanied with
snow. This uncertainty of the climate of Germany is
undoubtedly the principal cause that, notwithstanding
the healthfulness of its situation in other points of view,
and though in general people attain there to a consider-
able age, instances of very great age occur much more
rarely than in neighboring countries lying almost under
the same degree of latitude.

VII. Too high a degree of dryness, as well as too
great moisture, are unfavorable to duration of life. Air,
therefore, which contains a mixture of fine moisture, is
the best for attaining to great age. The reasons are as
follow : Moist air, being in part already saturated, has
less attractive power over bodies ; that is to say, con-
sumes them less. Besides, in a moist atmosphere there
is always more uniformity of temperature ; and fewer
rapid revolutions of heat and cold are possible. Lastly,
.an atmosphere somewhat moist keeps the organs longer
pliable and youthful ; whereas that which is too dry
brings on much sooner aridity of the vessels, and all the
characteristics of old age.

A most striking proof of this is afforded by islands ;
for we find that these, as well as peninsulas, have at all
times been, and still are, the cradles of old age. In
islands mankind always become older than in continents
lying under the same degree of latitude. Thus men
live longer in the islands of the Archipelago than in the
neighbouring countries of Asia; in Cyprus, than in
Syria ; in Formosa and Japan, than in China ; and in
England and Denmark, than in Germany.

Salt water also is more favourable to longevity than

fresh ; and for that reason seafaring people can become
so old. Stagnated fresh water, on the other hand, is
hurtful, by its mephitic evaporation.

VIII. A great deal seems to depend likewise on the
ground and soil, in a word, on the whole genius loci ;
and in this respect a cold soil appears to be the least
calculated to promote longevity.

IX. According to experience, England, Denmark,
Sweden, and Norway, are the countries where men at-
tain to the greatest age ; and we find by accurate obser-
vation, that all the before-mentioned properties are in
these united. On the other hand, Abyssinia, some parts
of the West Indies, and Surinam, are countries where
the life of man is shortest.

X. The more a man follows Nature, and is obedient
to her laws, the longer he will live; the further he
deviates from these, the shorter will be his existence.
This is one of the most general of laws. In the same
districts, therefore, as long as the inhabitants lead a
temperate life, as shepherds or hunters, they will attain
to old age ; but as soon as they become civilized, and
by these means sink into luxury, dissipation, and cor-
ruption, their duration of life will be shortened. It is,
therefore, not the rich and great, not those who take
gold tinctures and wonder-working medicines, who be-
come old ; but country labourers, farmers, mariners, and
such men as perhaps never in their lives employed their
thoughts on the means which must be used to promote
longevity. It is among these people only that the most
astonishing instances of it are to be observed.

XI. The most dreadful degree of human mortality,
occasioned by two inventions of modern times, is to be

100 ART OF PROLONGING LIFE.

found among the slaves in the West Indies, and in
hospitals for foundlings. Of the negro slaves, one in
five or six dies annually ; a proportion equal to that
which takes place during the ravages of the most in-
veterate pestilence. And of 7000 children who are
every year brought into the foundling hospital at Paris,
180 only are alive at the end of ten years ; so that 6820
perish, and no more than one in forty escapes from that
sepulchre. Is it not highly worthy of remark, and a
new proof of our former position, that mortality prevails
in the greatest degree where men deviate farthest from
Nature ; where her most sacred laws are despised ; and
where her first and strongest bonds are torn asunder ?
Where man, in the most evident manner, sinks below
the brute, there the child is dragged from its mother's
breast, and consigned helpless to the care of hirelings ;
there one brother is separated from another, from his
home, from his native soil, and transferred to a strange
and unhealthy climate, where, without hope, without
comfort, and without enjoyment, while his heart con-
tinually sighs after those he left behind, he pines to
death, oppressed with severity and labor. I am ac-
quainted with no contagion, no plague, no state of man-
kind, either in ancient or modern times, during which
mortality prevailed to the degree which it does in or-
phan-houses. To produce this evil required an excess
of refinement reserved only for the most modern times.
It required the aid of those wretched political calcula-
tors who can assert that the State is the best motheiy
and that nothing more is necessary to increase popula-
tion than to declare children to be its property, to place
them under its protection, and to establish a public abyss,

which may swallow them up. People now see, when it
is too late, the horrid consequences of this unnatural
maternity; this contempt of the first grand pillar of
human society, marriage and parental duty. In so
dreadful a manner does Nature avenge every trans-
gression of her most sacred commands.

XII. The result of all experience, and a principal
ground of longevity, is, omnia mediocria ad vitam pro-
longandam sunt utilia. Moderation in very thing, the
aurea mediocritas, so much extolled by Horace, and
which Plume calls the best thing on earth, is indeed of
the utmost efficacy in prolonging life. In a certain
mediocrity of condition, climate, health, temperament,
constitution, employment, spirits, diet, etc., lies the
greatest secret for becoming old. By all extremes,
either too much or too little, too high or too low, pro-
longation of life is impeded.

XIII. The following circumstance also is worthy of
remark. All those people who have become very old,
were married more than once, and generally at a very
late period of life. There is not one instance of a bach-
elor having attained to a great age. This observation
is as applicable to the female as to the male sex ; and
hence it would appear that a certain abundance in the
power of generation is favorable to longevity. It forms
an addition to the vital power ; and this power of pro-
creation seems to be in the most intimate proportion to
that of regenerating and restoring one's self; but a cer-
tain regularity and moderation are requisite in the em-
ployment of it ; and marriage is the only means by
which these can be preserved.

102 ART OF PROLONGING LIFE.

The greatest example of this is a Frenchman, named
De Longueville, who lived to the age of 110. He had
been married to ten wives ; his last wife he married
when in his ninety-ninth year, and she bore him a son
when he was in his hundred-and-first.

XIV. More women than men become old ; but men
only attain to the utmost extent of longevity. The
equilibrium and pliability of the female body seem, for
a certain time, to give it more durability, and to render
it less susceptible of injury from destructive influences.
But male strength is, without doubt, necessary to arrive
at a very great age. More women, therefore, become
old ; but fewer very old.

XV. In the first half of man's age, an active, even a
fatiguing life, is conducive to longevity ; but in the last
half, a life that is peaceful and uniform. No instance
can be found of an idler having attained to a remarka-
bly great age.

XVI. Rich and nourishing food, and an immoderate
use of flesh, do not prolong life. Instances of the great-
est age are to be found among men who from their
youth have lived principally on vegetables, and who
perhaps never tasted flesh.

XVII. A certain degree of cultivation is physically
necessary for man, and promotes duration of life. The
wild savage does not live so long as man in a state of
civilization. ,

XVIII. To live in the country and in small towns, is
favorable to longevity : to live in great towns is unfa-
vorable. In great cities, from one in twenty-five to one
in thirty die every year ; in the country, from one in

forty to one in fifty.* Mortality among children is in
particular much increased by living in great cities, so
that one half of those who are born die generally before
the third year; whereas, in the country, the half are not
carried off until the twentieth or thirtieth.f The small-

* The data upon which Hufeland founded these statements
were of a very inefficient character, as compared with those which
we possess at the present day, in the labors of the Registrar-Gen-
eral. Thus, instead of the mortality of large cities ranging from
1 in 25 to 1 in 30, the highest known rate of mortality, namely
that of Liverpool, is 1 in 30 ; while in the metropolis of London
it is only 1 in 40. In the country, taking as examples, Kent,
Surrey, and Northumberland, it ranges between one in 51, and 1
in 71 1-2. In further illustration of this subject, I have selected
the following examples from the Registrar-General's Report on

of children, nearly one half of all that are born alive die before
the end of the fifth year in Liverpool ; while the same number in
London live to the age of 33 ; and in the county of Surrey to 50.
In 1845 nearly one half of all the children born in Birmingham
died under five years of age ; the entire half in Manchester died
in the same period ; and more than one half in Liverpool. In
London the proportion was between one half and one third ; and.
in Wales less than one third. EDITOR.

est degree of human mortality is one in sixty annually;
and this proportion is found only here and there among
country people.*

XIX. Among some men a kind of renovation seems
to be really possible. In several instances of great age
it has been remarked that persons in their sixtieth or
seventieth year, when others cease to live, acquired
new teeth and new hair, and commenced as it were a
new period of life, which continued twenty or thirty
years longer : a kind of self-reproduction which is to be
observed only among the more imperfect part of the
creation, t

The most remarkable instance of this kind with which
I am acquainted, is an old magistrate named Bamberg,
who lived at Rechingen in the Palatinate, and who died,
in 1791, in the 120th year of his age. In 1787, long
after he had lost all his teeth, eight new ones grew up.
At the end of six months they again dropped out, but
their place was supplied by other new ones, both in the
upper and lower jaw ; and Nature, unwearied, continued
this labor four years, and even till within a month of
his death. After he had employed his new teeth for
some time with great convenience in chewing his food,

* In Northumberland, as is shown in the above table, it is 1 in

t In my work on " Healthy Skin " I have mentioned several in-
stances of very old persons in whom the natural color of the hair
returned after they had been for years before grey. This was the
case with John Weeks, who lived to the age of 114. Sir John
Sinclair reports a similar occurrence in an old Scotchman, who
lived to be 110; and Susan Edmonds, when in her 95th year,
Tecovered her black hair, but became again grey previously to her
death, at the age of 105. EDITOR.

NATURAL DURATION OF LIFE. 105

they took their leave, and new ones immediately sprang
up in some of the sockets. All these teeth he acquired
and lost without any pain ; and the whole number of
them amounted at least to fifty.

By the observations already made, we are now ena-
bled to come to a conclusion respecting the important
question : What is the proper term or 'boundary of
human life ? One might believe that some degree of
certainty could be acquired on this point; but it is in-
credible what difference in opinion respecting it prevails
among philosophers. Some allow man a very long, and
others a very short duration of life. Some are of
opinion that, to determine it, nothing is necessary but
to examine to what extent it is carried among savages,
because in that state of Nature the utmost period of
life must be discovered with the greatest precision.
This, however, is false. It ought to be considered that
this state of Nature is likewise, for the most part, a
state of misery, where the want of society and civiliza-
tion obliges men to waste themselves, and to undergo
fatigue superior to their strength ; and where, in conse-
quence of their situation, they are exposed to more
destructive influences, and enjoy much fewer means of
restoration. We must not take our examples from the
class of savages ; for these, in their properties, partici-
pate with the inferior animals : but from that class
where man, by culture and civilization, has really be-
come a rational being ; for he has then in a physical
sense first attained to his destination and preeminence,
and, by the help of reason, has procured those means
of restoration from without, and that happiness of situ-
ation, which it is possible for him to acquire. It is then

106 ART OF PROLONGING LIFE.

only that we can consider him as a man, and collect
examples from his condition.

One might also believe that death by marasmus, that
is to say, by old age, is the true boundary of human
life. But this reasoning, in the present times, is at-
tended with great deception ; for, as Lichtenburg says,
men have found out the art to ingraft old age upon
themselves before the time ; and one may see very old
people of thirty or forty, who have every symptom of
extreme age, such as stiffness and aridity, weakness,
grey hair, ossified cartilages, etc., which are observed
very rarely but among persons who have attained to
the age of eighty or ninety. This, however, is an arti-
ficial relative old age ; and such a standard cannot be
employed in a calculation which has for its object the
duration of the life of man in general.

Some, therefore, have invented the most singular
hypotheses to answer this question. The ancient Egyp-
tians, for example, believe that the heart increased two
drachms annually in weight for fifty years, and de-
creased again fifty years in the same proportion. In
the hundredth year, according to this supposition, no
more heart remained ; and, consequently, the hun-
dredth year was the term or boundary of human life.
To answer this question in a satisfactory manner, one
must, in my opinion, make the following essential dis-
tinction :

1. How long can man exist, in general, considered
as a race ; and what is the absolute duration of his life ?
We know that each class of animals has a certain abso-
lute duration of life, and the case must be the same
with man.

NATURAL DURATION OF LIFE. 107

2. How long can man live as an individual; and
what is the relative duration of his life ?

With regard to the first question, the research re-
specting the absolute duration of human life, there is
nothing to prevent us from giving it the utmost extent
to which, according to experience, it is possible for it to
attain. It is here sufficient to know what man's nature
is capable of; and a man who has attained to the far-
thest .boundary of mortal existence, may be considered
as a pattern of human nature in its utmost perfection,
and as an instance of what is possible for it under favor-
able circumstances. Now, experience incontestably
tells us, that a man still may attain to the age of 150
or 1 60 years, ; and what is of the greatest importance
is, that the instance of Thomas Parr, whose body was
opened in his 152nd year, proves that, even at this ajc,
the state of the internal organs may be so perfect and
sound that one might certainly live some time longer ;
and that no doubt would have been the case with him,
had not the manner in which he lived, by his not being
accustomed to it, brought on a plethora which proved
mortal. We may, therefore, with the greatest proba-
bility, assert, that the organization and vital power of
man are able to support a duration and activity of 200
years.

This assertion Acquires some weight by our finding
that it agrees with the proportion between the time of
growth and the duration of life. One may lay it down
as a rule, that an animal lives eight times as long as it
grows. Now, man in a natural state, where the period
of maturity is not hastened by art, requires full twenty-

108 ART OF PROLONGING LIFE.

five years to attain his complete growth and conforma-
tion ; and this proportion also will give him an absolute
age of 200 years.

It needs not be objected that great age is the unnatu-
ral state, or an exception from the rule ; and that a
shorter life is properly the natural condition. We shall
see hereafter, that almost all those kinds of death which
take place before the hundredth year are brought on arti-
ficially, that is to say, by disease or accident ; and it
is certain that the far greater part of men die an unna-
tural death, and that not above one in a thousand attains
to the age of a hundred years.

But with regard to the relative duration of human
life : that, indeed, is extremely variable, and as differ-
ent as each individual. It is regulated according to the
goodness or badness of the mass of which the person is
formed ; his manner of living ; speedier or slower con-
sumption ; and a thousand internal and external cir-
cumstances which may have an influence on the contin-
uance of his existence. We must not imagine that every
man, at present, brings with him into the world a vital
stock capable of lasting 150 or 200 years. It is unfor-
tunately the fate of our generation, that the sins of the
father often communicate to the embryo a far shorter
stamen vitce.* Let us only reflect on the innumerable
host of diseases and accidents which openly and secretly
prey upon our lives, and we sjiall clearly see that it is
now far more difficult than ever to attain to thaU term
which human nature is really capable of reaching.
That term, however, we must make our foundation ;

and we shall afterwards examine how far it may be in
our power to remove those obstacles which prevent us
at present from arriving at it.

The following table, founded on experience, may
serve as a proof of the relative duration of human life
at present.

More particular examination of human life. Essential definition of
it. Principal operations on which it depends. Accession from
without. Assimilation and Animalization. Nutrition and prepa-
ration of the organized matter. Power and organs consumed by
life itself. Separation and destruction of exhausted parts. Organs

of the life of man. Influence of reason and the higher powers of

fitted for long life than animals, mortality, however, should be
greater ?

WE now come to our principal object, the application
of the foregoing premises to the prolongation of human
life. But before we can be able to accomplish this
point, we must first thoroughly examine the following
questions : In what does the life of man properly con-
sist ? On what organs, powers, and disposition of parts
does this important operation, and the duration of it,
depend ? In what does it essentially differ from the
life of other creatures and beings ?

Man, without doubt, is the highest link, the crown of
the visible creation ; the last, the most complete, and
the best finished production of the plastic power of Na-
ture ; the highest degree of its self-representation which
our eyes are capable of seeing, or our senses of com-
prehending. With him our sublunary prospect is closed ;
he is the extreme point with which and in which the
sensible world borders on a higher spiritual world.

ESSENTIAL DEFINITION OF LIFE. Ill

The organization of man is, as it were, a magic band,
by which two worlds of a totally different nature are
connected and conjoined ; an eternally incomprehensi-
ble wonder, by which he becomes, at the same time, an
inhabitant of these two worlds, the material and the in-
tellectual.

One may, with propriety, consider man as a compen-
dium of Nature ; as a masterpiece of conformation, in
which all the active powers scattered throughout the
rest of Nature, all kinds of organs and forms of life, are
united in one whole, act in concert, and, by these means,
make him, in the strictest sense, a little world ; a copy
and epitome of the greater, as he was so often called by
the ancient philosophers.

His life is the most expanded ; his organization the
most delicate and best finished; his juices and compo-
nent parts the most ennobled and best prepared ; and
his intensive life and self-consumption are, therefore, the
strongest. He has, consequently, more points of con-
tact with the whole of Nature by which he is sur-
rounded, and likewise more wants ; but he has, also, a
richer and more perfect restoration than any other being.

The inanimate mechanical and chemical powers of
Nature ; the organic or living powers ; and that spark
of divine power, the power of thought, are here
united and blended together, in the most wonderful
manner, to form that godlike phenomenon which we call
the life of man.

Let us now take a short view of the essence and me-
chanism of this operation, as far as they can be dis-
covered.

The life of man, considered in a physical view, is

112 ART OF PROLONGING LIFE.

nothing else than an incessant ceasing and being ; a
continual change of destruction and restoration ; an
everlasting contest of chemical, decomposing powers,
with all the combining and creative vital powers. New
component parts are every moment collected from the
whole of nature that surrounds us ; called to life from
an inanimate state, and transferred from the chemical
to the organic living world ; and from these heteroge-
neous particles the plastic vital power produces a new
uniform mass, which, in every point, is stamped with
the character of life. But, in the same unceasing man-
ner, the exhausted, worn-out, and corrupted component
parts, when their combination is dissolved, become sub-
ject again to the mechanical and chemical powers,
which are in continual contest with the living powers ;
return from the organic to the chemical world ; and
again become a part of inanimate nature in general,
from which they had been separated for a short time.
This uninterrupted business is the work of the vital
power ever active within us ; and is, consequently, at-
tended with an incessant exertion of that power, which
is an important part of vital operation. Life, there-
fore, is a continual receiving, appropriation, and giv-
ing back ; an incessant mixture of death and new cre-
ation.

What then, in a common sense, we call the life of a
creature, considered as a representation, is nothing else
than a mere phenomenon, which has nothing peculiar
or self-sub^istent but the active spiritual power which
forms the ground of it, and which binds and regulates
the whole. All the rest is only appearance ; a grand
spectacle continued, where the thing represented does

ESSENTIAL OPERATIONS OF LIFE. 113

not remain the same a moment, but is incessantly
changing ; where the whole duration, form, and figure
of the representation depend, in a particular manner, on
the matter employed, which is always varying, and on
the manner in which it is used ; and the whole phenom-
enon can exist no longer than the continued influx from
without, which supplies nourishment for the process.
Its analogy with a flame is, therefore, very great ; only
that the latter is merely a chemical, and life a chemico-
animal process, a chemico-animal flame.

The life of man then, according to its nature, depends
on the following grand operations :

I. Accession and reception of vital nourishment from
without.

By nourishment is here meant not merely what we
call food and drink, but much rather that influx, from
the atmosphere, of subtle, spiritual, vital nourishment,
which seems in a particular manner to contribute to-
wards the support of the vital power, especially as the
former coarse nourishing substances serve more for
supporting and repairing the matter of the body and of
its organs ; in a word, not that alone which passes
through the mouth and the stomach, since our lungs and
skin receive an abundance of vital nourishment, and,
for spiritual support, are of much greater importance
than the stomach.

II. Appropriation, assimilation^ and animalization ;
transition from the chemical to the organic world,
through the influence of the vital power.

Every thing that enters our bodies must first obtain
the character of life before it can be called ours. All
component parts, nay, the most subtle agents of Nature,
8

114 AIIT OF PROLONGING LIFE.

which flow into us, must be animalized ; that : is to say,
be so modified and combined, in a totally new manner,
by the help of the vital power, that they no longer act
according to the laws of inanimate and chemical nature,
but according to the peculiar laws of organic life, and
support themselves in opposition to others. In short,
as component parts of a living body, they cannot be
considered singly, but always as compounded according
to their proper nature and the laws of the vital power.
Every thing in us, even chemical and mechanical pow-
ers, is, therefore, animalized ; and this, for example, is
the case with electricity, and oxygen or vital air. As
goon as they are made component parts of a living
body, they become compounded nature (animalized
electricity, animalized oxygen,) and cannot be consid-
ered merely according to the laws and influence which
they had in common nature, but as subject to, and act-
ing under specific organic laws. These observations
are applicable not only to oxygen, but also to other new
chemical discoveries. But we must beware of ascrib-
ing to them the same effects in the vital combination of
our bodies, as those which we perceive them to have in
the atmosphere ; for they act according to different and
specific laws. This observation, in my opinion, cannot
be too often repeated ; and it alone may guard us from
error in the highly important application of the princi-
ples of chemistry to organic life. We, without doubt,
have these chemical powers and agencies within us, and
a knowledge of them is indispensably necessary ; but
their method of operating in our bodies is modified in
another manner, as they find themselves in a woild
altogether different.

ESSENTIAL OPERATIONS OF LIFE. 115

This important business of assimilation and animali-
zation is the employment, first of the absorbing and
glandular system, in its widest latitude ; not merely of
the lacteal vessels, but also of the absorbing vessels of
the skin and the lungs, which may be called the vesti-
bule, through which every thing that is to form a part
of us must pass ; and, secondly, of the system of circu-
lation, by which the component parts are prepared and
brought to organic perfection.

III. Nutrition ; configuration of the animalized
component parts ; farther ennobling of them.

The component parts, fully animalized, are now in-
corporated and changed into organs ; and this opera-
tion is the business of the plastic power. By the pre-
paration of the finer and more perfect secreting vessels,
these organized component parts are brought to their
highest degree of purification and refinement ; through
the brain as nervous fluid, and through the organic sys-
tem as organic juices, both of which are a combination
of the purest organic matter, with a rich abundance of
vital power.

IV. Self-consumption of the organs and poioers by
vital exertion.

Active life itself is an incessant exertion of agency
and power ; and, consequently, attended with a contin-
ual waste of power and consumption of the organs.
Every thing in which the power shows itself as an
agent, and active, is exertion ; for no vital exertion, not
even the smallest, can be made without excitation and
reaction of the power. This is a law of organic nature.
The voluntary and insensible internal movements, there-
fore, of circulation, chylification, assimilation, and secre-

116 ART OF PROLONGING LIFE.

tion, as well as voluntary movements, and those pro-
duced by the operations of the mind, are continual
exertions of power, and are incessantly consuming both
the powers and the organs.

This part of life is of the utmost importance in re-
gard to its duration and condition. The stronger vital
consumption is, the speedier life will be wasted, and the
shorter must be its duration ; but if it be too weak, the
consequence then is too seldom a change of component
parts, imperfect restoration, and a bad habit of body.

V. Separation and new acquisition of component
parts ; transition of them from the organic to the chemi-
cal world, and their union again ivith inanimate nature
in general.

The component parts which have been used, and
which can no longer be retained in this combination,
again separate themselves from it. They lose the in-
fluence of the vital power, and begin to be decomposed,
to fly off, and to be once more united according to the
pure chemical laws of Nature. All our excretions,
therefore, carry with them the most evident traces of
decomposition, a process merely chemical, which, as
such, is never possible, in a state of real life. The
function of discharging these parts from the body is
committed to the organs of secretion and excretion,
which operate with continual activity ; the intestines,
kidneys, liver, and, in particular, the whole surface of
the skin and lungs. These perform real chemico-ani-
mal operations ; the removal of the parts is effected by
the vital power, but the productions are entirely chem-
ical.

These grand operations constitute life in general, and

ESSENTIAL OPERATIONS OF LIFE. 117

at every moment ; for they are continually united, con-
tinually present, and < inseparable from the vital opera-
tion.

The organs which belong to life have in part been
already mentioned. In the present point of view they
may be most conveniently divided into three classes :
Those which receive and prepare ; those which evacuate ;
and those which keep these contrary movements, as well
as the whole internal economy, in equipoise and order.
Many thousands of greater or smaller organs are con-
tinually employed in separating and throwing off the
particles which have been exhausted and corrupted by
the internal consumption. Besides the evacuating ducts,
properly so-called, the whole surface of the skin and
lungs is covered with myriads of secreting organs in
continual activity. Equally numerous and various are
the passages of the second class, those of restoration.
It is not sufficient that the decrease of the coarser parts
should be repaired from the nourishment by means of
the organs of digestion ; the lungs, the organs of respi-
ration, are also continually employed to draw in, from
the atmosphere, nourishment, vital heat, and vital power.
The heart, and the circulation of the blood, which is de-
pendent on it, serve to regulate their movements ; to
diffuse to all points the received heat and nourishment ;
and to drive off, through these passages of excretion,
those particles which have been used and exhausted.
All these operations are assisted by the influence of the
mental powers and their organs, which are the most
perfect in man. This, indeed, increases intensive life
and self-consumption, but at the same time it is a highly

118 ART OF PROLONGING LIFE.

important means of restoration, of which more imper-
fect beings are destitute.

One may form some idea of the extraordinary self-
consumption of the human body, when one reflects that
the pulsation of the heart, and the motion of the blood
connected with it, take place 100,000 times every day ;
that is to say, the heart and all the arteries are con-
tracted 100,000 times daily, with such force as is able
to keep a resistance of from fifty to sixty pounds of
blood in continual movement. What clock, what ma-
chine of the hardest iron, would not by such use be in
a short time worn out ? If we add to this the almost
equally incessant muscular motion of our bodies, which
must occasion a much greater wasting, as these parts
consist more of tender gelatinous particles, we may then
have a pretty just conception with what loss of sub-
stance a walk, for example of ten miles, or a rapid
journey of thirty, must be attended. And not only
soft and fluid parts, but even the hardest, are gradually
worn out by continual use. This may be clearly per-
ceived in the teeth, which are evidently destroyed by
long use, and which, on the other hand, by being not
used, that is, not exposed to antagonists, become exceed-
ingly long. It is proved that, in this manner, we should
be very soon destroyed were there no reparation ; and
it has been estimated, with great probability, that every
three months our bodies are no longer the same, but
consist of entirely new particles.

But equally wonderful and extraordinary is the con-
tinual reparation of those parts which have been lost.
This may be readily comprehended ; because, notwith-

REPARATIVE POWERS OF LIFE. 119

standing the incessant loss which we sustain, our mass
still continues the same. The fluid parts, however,
regenerate themselves soonest; and experience has
taught us, that the greatest loss of blood may be again
repaired in fourteen days. The solid parts reproduce
themselves by the same power and mechanism as are
employed in their first creation ; the gelatinous nourish-
ing principle is conveyed by circulation to every part
of the body, and is organized according to the plastic
laws of the different parts. The bones even which are
the hardest become regenerated, as is proved in the
experiment with madder, by the use of which the bones
in a short time become red. Whole bones lost or
decayed can renew themselves also; and one finds
sometimes with astonishment, in pieces of ivory, the
hardest animal body, leaden bullets, which must have
been lodged in them by a shot, and which are entirely
surrounded with solid bone.*

* The fact is true, but the explanation removes the wonder.
That a bullet should perforate solid ivory, and that the vacuity
caused by its passage should close up and become firm and solid
is, of course, impossible. The explanation of the phenomenon
is as follows : The tusk of the elephant continues to grow as
long as the animal lives ; for this purpose it is furnished with a
permanent producing organ, or pulp, which occupies the root of
the tusk. The pulp is conical in shape, and, as it is constantly
engaged in forming successive layers of ivory, the tooth is grad-
ually pushed forwards, in other words, it grows. Now, if a bullet
enter the substance of this pulp it will, in time, by a common
process of expulsion of foreign bodies, reach the surface of the
pulp ; and, when that is effected, the next layer of ivory formed
by the pulp will be deposited between the pulp and the bullet ;
so that now the bullet is not only excluded from the pulp, but

120 ART OF PROLONGING LIFE.

The usual progress or history of human life is, in a
few words, as follows :

The heart, the grand source of all vital motion as
well as vital diffusion, and the grand principle of the
excreting as well as renovating operations, becomes
always smaller in proportion to the increase of age ; so
that, at length, it occupies an eighth part of the space
which it did in the beginning of life.* Its substance
also becomes always thicker and harder ; and its irrita-
bility becomes in the same proportion less. The active
powers then decrease more and more every year ; and
the retarding powers, on the other hand, increase. The
same thing takes place in the whole vascular system,
and the organs of motion. All the vessels become
gradually harder, narrower, more shrivelled, and unfit

the pulp has covered it over with a layer of ivory, and as layer
after layer of new ivory is formed, the bullet becomes more and
more deeply buried, more and more removed from the pulp, and
eventually may be found in the solid substance of the ivory
several inches, or even feet, distant from its original bed.
EDITOR.

* Hufeland must have meant " an eighth less space ; " he
could hardly have intended to make a statement so perfectly
erroneous as the above, upon a point so easily put to the proof.
The heart, undoubtedly, diminishes a little in size in healthy old
age ; becomes firmer in texture, and less frequent in its pulsa-
tions ; adapting itself in fact to the smaller volume of blood con-
tained within the body; but the amount of diminution is very
trifling. In a preceding page (106), the author ridicules, very
justly, the hypothesis of the ancient Egyptians concerning the
decrease of the heart ; and in the examination of Thomas Parr,
to which lie also refers (p. 87), the heart, so far from being
diminished in size, was found to be "great, thick, fibrous, and
fat." EDITOR.

CESSATION OF LIFE. 121

for use ; the arteries are ossified and a great many of
the finer vessels are entirely closed up.

The following, therefore, are the unavoidable conse-
quences :

1st. By this closing up and becoming shrivelled, the
most important and finest organs of vital regeneration,
the passages for assimilation and external accession, the
lungs, skin, absorbing and lacteal vessels become de-
ranged ; and, consequently, the addition of nourishing
and enlivening component parts from without is ren-
dered weaker. Nourishment can neither be received
in such quantity, nor be prepared and diffused so well
as before.

2nd. By this increasing hardness and aridity of the
vessels they lose more and more their power of move-
ment and sensation. Irritability and sensibility decrease
always in the same proportion as the former increase ;
and the active and spontaneous powers within us always
give more place to the destructive, mechanical, and
chemical powers.

3rd. By the decrease of the motive power, and the
closing up of innumerable vessels, excretion, the most
indispensable cause of our continual purification, and of
the removal of corrupt particles, principally suffers.
The skin, its most important organ, becomes with
years always closer, more impenetrable, and less useful.
This is the case also with the kidneys, the pores of the
intestines, and the lungs. The juices, therefore, in old
age, must be always more impure, more acrid, tougher,
and more impregnated with earthy particles. Earth,
the great enemy of vital motion, acquires in our bodies,
by these means, a preponderance; and thus, with a

122 ART OF PROLONGING LIFE.

living body, we insensibly approach our final destina-
tion : " Return to the earth from which thou wast
taken ! "

In this manner does life bring on a cessation of life,
that is, natural death ; and its progress is as follows :

The powers subject to the will first decrease, and
then the spontaneous and proper vital movements. The
heart can no longer force the blood to the extremities ;
pulsation and heat leave the feet and hands ; but the
blood is still kept in motion from the heart and larger
vessels, and thus the vital flame, though weak, is for
some time preserved. At length, the heart has not
strength to press the blood through the lungs. Nature
now employs all her power to invigorate respiration,
and by these means to give some passage to the blood.
This power, at last, is exhausted ; the left ventricle of
the heart, consequently, receives no more blood, and is
no longer irritated, and continues at rest. The right
still receives a little transmitted to it from parts already
half dead ; but these parts soon become perfectly cold ;
the juices* curdle ; the heart receives heat no more, all
its motion ceases, and death is complete.

Before I proceed further I must examine some prob-
lematical circumstances, which present themselves in
the course of every research into the duration of human
life, and which are deserving of particular attention.

The first problem is : How is it possible that man,
whose organization is the most delicate and most com-
plex, whose self-consumption is the most rapid, and
whose duration of life ought consequently to be the
shortest, should, however, exceed so evidently, in duration
of life, all classes of the more perfect animals, which

SUPERIOR DURATION OF HUMAN LIFE. 123

have the same size, the same organization) and the same
place in the scale of creation ?

It is well known that the more imperfect the organi-
zation, the greater is the duration of life, or at least the
vital tenacity. Man, as the most perfect of all
creatures, ought consequently, in this respect, to be far
inferior to others. Besides, it appears from the forego-
ing research, that the duration of life of an animal will
be shorter the more numerous its wants are for support-
ing that life. Of these, man without doubt has the
greatest number, and this is a new ground for a shorter
duration. It has been likewise shown already that,
among animals, the highest degree of self-consumption
is the process of generation, and that it shortens in a
very sensible manner their duration of life. In this
the perfection of man is remarkably apparent ; and ii
him there is also a new kind of generation, the spiritual,
or the business of thinking; and his duration must
thereby suffer still more.

It may be asked, then, by what means has man such
a superiority in regard to the duration of life ?

In my opinion, the question may be answered from
the following grounds :

I. The texture of the whole cellular membrane is
much softer and tenderer in man than in animals of the
same class. Even the so-called nervous coat of an
intestine is, in a dog, much harder, and cannot be
so inflated as that of a man. The veins also, the bones,
and the brain, are, in animals, much more solid, and
abound with a greater quantity of earth. Now, I have
before shown that too great a degree of hardness or
brittleness in the organs is prejudicial to duration of

124 ART OF PROLONGING LIFE.

life, because the organs thereby lose sooner their plia-
bility and fitness for use ; and because that stiffness and
aridity which bring on old age, and at length a com-
plete stoppage of the whole machinery, are thus
hastened ; man, consequently, must have old age later,
and a more extensive period of life.

II. Man grows more slowly ; attains later to matu-
rity ; all his powers are longer in expanding ; and I
have before shown, that the existence of a creature is
lengthened in proportion to the time required for its
expansion.

III. Sleep, the greatest means of vital retardation
and support, is in man more peculiarly regular and
constant.

IV. The perfect organization of the soul,* the fac-
ulty of thinking, that is, reason, makes in man a very
great difference.

This higher and divine power, which exists in man
alone, has the most visible influence, not only on his
character in general, but also on the perfection and
duration of his life ; and in the following manner :

1st. It is perfectly natural that the sum of the active

* I hope my readers will not here misunderstand my mean-
ing, and imagine that I reckon the soul to be a part, a produc-
tion, or property of the body. This is by no means the case.
The soul, in my opinion, is something distinct from the body ; a
being of a totally different, more exalted, intellectual world ; but
in this sublunary combination, and to be a human soul, it must
have organs to fit it not only for action, but also for sensation,
and even for the higher functions of thinking and combining
ideas. The first cause of thought is, therefore, spiritual ; but the
business of thinking itself, as carried on in this mortal machine, is
organic.

SUPERIOR DURATION OF HUMAN LIFE. 125

vital powers within us should be increased by the
assistance of this most pure and divine power.

2d. Man, by the most refined and most perfect
organization of the brain, acquires an entirely new
organ of restoration peculiar to himself; or rather, his
whole vital capacity is thereby increased.

3d. By this highly perfect power of the soul, man
enters into connection with an entirely new world
the spiritual ; which is concealed from the rest of the
creation. It gives him points of contact altogether
new new influences, and a new element. Might not
one in this respect call man an amphibious being (par-
don the expression) of a higher kind, for he is a being
who lives at the same time in two worlds, the material
and the intellectual; and apply to him what I have
shown from experience, respecting amphibious animals,
that existence in two worlds at the same time prolongs
life ? What an immense ocean of spiritual nourishment
and spiritual influences is opened to us by this higher
and more perfect organization. An entirely new class
of means to nourish and excite the vital power, pecu-
liar to man alone, here presents itself. I mean the
more refined mental and more exalted moral sensations
and affections. I shall, on this occasion, mention .only
the enjoyment and comfort which lie in music ; the art
of painting, and the enchantments of poetry, and the
imagination ; the pleasure which attends the investiga-
tion of truth or a new discovery ; the rich source of
happiness that may be found in the idea of futurity ; in
the power of anticipating it, and of living, through hope,
when the scenes now present shall be no more. What
comfort, what unshaken firmness may we not acquire

126 ART OF PROLONGING LIFE.

from the single idea and belief of immortality. In short,
the circle of human life is hereby extended in an aston-
ishing manner ; and man actually derives his vital sub-
sistence from two worlds at the same time, the material
and the immaterial, the present and the future. His
duration of life must, therefore, necessarily be a gainer.

4th. The more perfect powers of the soul contribute
also so far to the support and prolongation of life, that
man thereby is made a partaker of reason, which enables
him to regulate his conduct in all things ; which mode-
rates instinct, a faculty merely animal, as well as the
furious passions, and the rapid consumption connected
with them ; and which, by these means, is able to pre-
serve him in that middle state which we have already
shown to be so necessary for long life.

In short, man evidently has more spiritual part than
was requisite for him in the present world; and this
superabundance of spiritual power carries with it, as it
were, the bodily. It is the bodily only, which is sub-
ject to wasting, and to death.

I cannot here omit to remark, how apparently the
moral object, the higher destination of man, is interwo-
ven with his physical existence : and how reason and
the t higher powers of thought, which properly render
him a man, display not only his moral, but his physical
perfection ; consequently, a proper cultivation of his
spiritual powers, particularly the moral, makes him,
beyond all dispute, more perfect, not only morally, but
also physically ; and, as we shall have occasion to see
hereafter, increases his vital capacity and vital dura-
tion. The man merely savage sinks, in regard to
duration of life, to the level of the inferior animals,

SPIRITUALITY OF HUMAN LIFE. 127

with which he is on an equality as to size and strength ;
while, on the other hand, the weakest man, by this
spiritual subsistence, can often prolong his life far
beyond that of the strongest animal.

From the same principles we can resolve also the
second problem : How comes it that among men, whose
duration of life so far exceeds that of animals, and
who, as experience shows, can live to an extraordinary
age, so few attain to their real term of existence, and
that the greater part of them die before the time ; or, in
other words, that where the longest duration is possible,
there mortality is the greatest.

The great softness and tenderness of the organs,
which render man more capable of long duration,
expose his life also to more dangers, to more interrup-
tions, to more derangements, and to more injuries.

Besides, the more points of contact he has with the
whole of surrounding Nature, he is rendered the more
susceptible of a multitude of prejudicial influences
which a coarser organization does not feel. The grati-
fication of his multiplied wants multiplies his dangers.

Even the spiritual life is attended with its peculiar
poisons and dangers. What knows an animal of de-
luded hope, disappointed ambition, slighted love, care,
repentance, or despair? And how destructive and
pernicious to the life of man are these poisons of the
mind!

Lastly, one main point is, that man, though organ-
ized for a reasonable being, is, however, at liberty to use
his reason or not; animals, instead of reason, have
instinct ; and, at the same time, are far more insensible
and callous in regard to destructive impressions.

128 ART OF PROLONGING LIFE.

Instinct teaches them to use that which is good for
them, and to shun that which hurts them. It tells them,
when they have enough, when they require rest, when
they are indisposed. Instinct, without the help of regi-
men, secures them from intemperance and dissipation.
Among men, on the other hand, every thing, even what
concerns medicine, is referred to reason. Man has
neither instinct to guard against error, nor resolution
enough to withstand it. All this ought to be supplied
by reason. If that be wanting, or if he neglect to
listen to its admonition, he loses his only guide, his
greatest means of support ; and sinks, physically, not
only to the level of the brute, but even below it,
because brutes are indemnified by Nature for the want
of reason in regard to their vital support. Man, on
the contrary, without reason, is a prey to every noxious
influence, and becomes the most perishable and corrup-
tible being under the sun. The natural want of reason
is far less prejudicial to the support and duration of life
than the interrupted exercise of it, where it has been
bestowed by Nature. But, as Haller, with so much
truth, says,

O wretched being, to thy interest blind,
.In whom the angel and the brute are join'd !
God gave thee reason to direct thy choice ;
Yet thou thy ear turn'st from its friendly voice.

In this lies the principal cause why among men, who in
every respect are best fitted for long life, mortality is
greatest.

One need not object that this assertion is contradicted
by many madmen who live to a great age. The first

MORTALITY OF MAN. 129

thing to be considered here is the species of insanity.
If it be attended with rage and fury, these certainly
shorten life very much ; because they are accompanied,
in the highest degree, with exertion of the powers and
vital consumption. And the case is the same with the
deepest melancholy and distress of mind, as these injure
the noblest organs, and destroy the powers. But in a
mean state, where reason is not entirely gone, where
the disorder displays itself by incoherent ideas, and
false but often very agreeable sports of the imagina-
tion, there the physical use of reason may continue,
while the moral is lost. Nay, a man in this state is to
be considered as one under the influence of a pleasant
dream, on whom a multitude of wants, cares, disagree-
able and life-shortening impressions, and even physical
causes of disease, as experience shows, produce no
effect ; who lives happy in his self-created world ; and
is far less exposed to destruction and vital consumption.
It is to be observed, in the last place, that when a luna-
tic is totally deprived of reason, those by whom he is
attended and taken care of, think for him, and as it were
lend him their reason. He is therefore supported by
reason, whether it be his own or that of another.

CHAPTER VIII.

Signs of long life in individuals. Sound stomach and organs of
digestion. Good teeth. Well-organized breast. Heart not too
irritable. Strong natural power of restoration and healing. Suffi-
cient quantity and diffusion of the vital power. Good tempera-
ment. Faultless and well-proportioned make of body. No partic-
ular weakness of any part. Portrait of a man destined to long
life.

AFTER explaining these general principles, I can
now proceed to lay down the special and individual
grounds of long life, which must exist in the man him-
self. I shall here, therefore, describe those grand pro-
perties, and that frame, which, according to experience
and the foregoing observations, must be possessed by
every man before he can lay claim to a long existence.
This sketch may, in some measure, serve as a register
of the signs of longevity.

The properties, which may be called the foundations
of long life in man, are the following :

I. Above all things, the stomach, and the whole sys-
tem of digestion, must be sound and well formed. It is
incredible of what importance this most powerful of all
the rulers in the animal kingdom is, in the above
respect ; and one may justly affirm, that, without a good
stomach, it is impossible to attain to a great age.*

* In a good stomach we have the secret of Thomas Parr's
great age ; in the report of his examination after death, it is

SIGNS OF LONG LIFE. 131

The stomach, in two respects, is the foundation of
long life. First, as it is the principal and most impor-
tant organ of the restoration of our nature ; the door
through which every thing that is to form a part of us
must enter ; and the first vessel on the good or bad con-
dition of which, not only the quantity, but also the qual-
ity of the addition made to our bodies must depend.
Secondly, because by the state of the stomach, the effect
even which the passions, the causes of disease, and other
destructive influences, have over our bodies, is modified.
" He has a good stomach," says the proverb, when one
wishes to characterize a person to whom neither grief,
care, nor sorrow, is prejudicial; and certainly in that
expression there is a great deal of truth. All these
passions must, in a particular manner, affect the stomach,
and must be felt by it before they can pass into, or in-
jure, our physical constitution. A strong robust stomach
is not susceptible of any impression from them : on the
other hand, a weak sensible stomach is every moment
subject to some derangement in its whole frame ; and,
consequently, the important business of restoration is
continually interrupted, and carried on in an imperfect
manner. The case is the same with most of the physi-
cal causes of disease. The greater part of them make
their first impression on the stomach : and, therefore, a
want of digestion is the earliest symptom of illness. It
is thus the first vessel by which they insinuate them-

stated that "his viscera were sound and strong, especially his
stomach ; and it was observed of him that he used to eat often,
both by night and by day, taking up with old cheese, milk, coarse
bread, small beer, and whey ; and what is most remarkable, he
ate at midnight, a little before he died." EDITOR.

132 ART OF PROLONGING LIFE.

selves into our bodies, and disturb the whole economy.
Besides, it is a principal organ, on which the equilib-
rium of the nervous motions, and in particular their
tendency to the periphery, depends. If it be power-
ful and active, morbid irritations cannot so easily fix
themselves : they are removed and driven off' through
the skin, before they effect a real derangement of the
whole system ; that is to say, before they bring on
disease.

A good stomach may be known two ways ; not merely
by an excellent appetite, for that may be the conse-
quence of any stimulus ; but, in particular, by an easy
and perfect digestion. Whoever feels that he has a
stomach, cannot have a good one. One must not be sen-
sible that one has eaten ; must not be drowsy, dejected,
or uneasy after meals ; must have no phlegm in the
throat in the morning ; and the evacuations must be
regular and well concocted.

We are taught, by experience, that all those who at-
tained to a very great age had a good appetite, which
they retained to the last.

For good digestion, good teeth are extremely neces-
sary ; and one, therefore, may consider them among the
essential properties requisite for long life, and in two
points of view. First, good and strong teeth are al-
ways a sign of a sound, strong constitution, and good
juices. Those who lose their teeth early, have, in a
certain measure, taken possession of the other world
with a part of their bodies. Secondly, the teeth are
a great help to digestion, and consequently to resto-
ration.

II. A well-organized breast and organs of respira-

HEART. PULSE. TEMPERAMENT. 133

tion. These may be known by a broad, full chest ; the
power of keeping in one's breath for a long time ; ;i
strong voice, and by being seldom subject to a cough.
Breathing is one of the most incessant and necessary
of the vital operations, the means of the most indis-
pensable, spiritual restoration ; and, at the same time,
the cause by which the blood is continually freed from
a multitude of corrupted particles. Those in whom
these organs are well formed, possess the greatest
assurance of longevity ; arid for this reason, because
an important passage, by which death and the causes
of destruction might insinuate themselves, is fully se-
cured. The breast is among the principal atria
mortis,* one of those parts of which death first lays
hold.

I If. A heart not too irritable. We have alrea<!
that a principal cause of our internal consumption, or
spontaneous wasting, lies in the continual circulation of
the blood. He who has a hundred pulsations in a
minute, must be wasted far more speedily than he who
has only fifty. Those, therefore, whose pulse is always
quick, and in whom every trifling agitation of the mind,
Or every additional drop of wine?, increases the motion
of the heart, are unfortunate candidates for longevity,
since their whole life is a continual fever; and the pro-
longation of it is thereby counteracted in a double
manner, partly by the speedier waiting connected with
it, and partly because restoration is impeded by nothing
go much as by an inee.s.-.'intly accelerated circulation.
A certain decree of rest is absolutely necessary, that
the nourishing particles may settle, and be converted

134 ART OF PROLONGING LIFE.

into the substance of our bodies. Such people, also,
will never become corpulent.

A slow, uniform pulse is, therefore, a strong sign of
Jong life, arid a great means to promote it.

IV. A sufficient quantity and diffusion of the vital
power. A good temperament. Calmness, order, and
harmony in all the internal operations and movements,
are of the utmost importance for supporting and pro-
longing life ; but these, in a particular manner, depend
on a proper state of the general irritability and sensi-
bility of the body ; and the latter qualities must be
neither too strong nor too weak, and be uniformly dif-
fused, so that no part may have too great or too small
a proportion. A certain degree of insensibility, a small
mixture of phlegm, are also ingredients highly neces-
sary for prolonging the duration of life ; as they lessen,
at the same time, self-consumption, favor a far more
perfect restoration, and contribute most effectually to
preserve our existence. A good temperament, there-
fore, may so far be the foundation of a long life. The
best is the sanguine, tempered with a little of the
phlegmatic. This produces a serene, cheerful mind,
moderate passions, undaunted courage, and, in short,
that state of soul which is most fitted for longevity.
The cause of this disposition is generally an abundance
of the vital power. And as Kant has already proved
that such a mixture of temperament is the properest
for attaining to moral perfection, I am of opinion that
one may reckon it among the best gifts of heaven.

V. A strong natural power of restoration and healing
by which all those losses which we daily sustain are not
only repaired, but repaired well. This depends, ac-

FAULTLESS CONFORMATION. 135

cording to the above principles, on a good digestion,
and a calm, uniform circulation of the blood. To these
may be also added a perfect and vigorous activity of
the absorbing vessels (the lymphatic system), and the
good condition and regular operation of the organs of
secretion. The effect of the former is, that the nour-
ishing substances pass easily into our bodies, and are
enabled to reach the places of their destination ; by the
latter, they are completely freed from all extraneous
and pernicious mixture, and enter us perfectly pure.
And this properly gives an idea of the most complete
restoration.

It is incredible how much this quality contributes
to the support of life. In a man who possesses it,
consumption may be exceedingly strong without his
sustaining much loss, as it is again repaired with the
utmost speed. We have, therefore, instances of men
who, even amidst a life of debauchery and fatigue, be-
came very old : and thus, for example, could a Duke de
Richelieu and a Louis XV. attain to a great age.

A- strong natural power of healing must also be united
with that of restoration ; or, in oilier words, that fac-
ulty of Nature by which it assists itself easily in cases
of derangement and interruption, keeps back and re-
moves the causes of disease, and favors the healing of
wounds. There is an astonishing power of this kind
in our bodies, as is shown by the example of savages,
who are scarcely subject to any diseases, and among
whom the most dreadful wounds heal up entirely of
themselves.

VI. An uniform and faultless conformation of the
ivhole body. Without uniformity of structure there can

136 ART OF PROLONGING LIFE.

be no uniformity of powers and motion, and without
these it is impossible to become old. Besides, an im-
perfect structure gives an easy opportunity for the rise
of local diseases which may bring on death. One will
not, therefore, find that an overgrown person ever at-
tained to a very great age.

VII. No part, no intestine must have a great degree
of weakness, otherwise such a part may serve to give a
ready admission to the causes of disease, to the first
seeds of some disorder or derangement, and become, as
it were,- the atrium mortis. Even where the organiza-
tion is very good and perfect, this may be a secret
enemy, from which destruction may be afterwards con-
veyed to the whole body.

VIII. The texture of the organization must be of a
mean quality ; strong and durable, but not too dry or
rigid. We have already seen, that, through all the
classes of organized beings, too great aridity or hard-
ness is prejudicial to the duration of life. Among men
it must be so in the highest degree ; because their
organization, according to their destination, is the ten-
derest of all, and, by a superfluity of earthy particles,
may be soonest rendered useless. These are injurious
two ways, partly by bringing on much sooner old age,
the grand enemy of life ; and partly by making the
finest organs of restoration much sooner unfit for dis-
charging their functions. Hardness of organization, in
order to favor long life, must not consist so much in
mechanical toughness as in hardness of sensation ; and
must not be the property so much of a coarser texture
as of the powers. The quantity of earth must be ex-
actly so great as to give sufficient elasticity and tone ;

FAULTLESS CONFORMATION. 137

but neither so large as to prove inflexibility, nor so
small as to occasion too much facility of movement ; for
both these are hurtful to duration of life.

Let me now be permitted to delineate the portrait of
a man destined to long life. He has a proper and well-
proportioned stature, without, however, being too tall.
He is rather of the middle size, and somewhat thick-set.
His complexion is not too florid : at any rate, too much
ruddiness in youth is seldom a sign of longevity. His
hair approaches rather to the fair than the black ; his
skin is strong, but not rough. His head is not too big ;
he has large veins at the extremities, and his shoulders
are rather round than flat. His neck is not too long ;
his abdomen does not project ; and his hands are large,
but not too deeply cleft. His foot is rather thick than
long ; and his legs are firm and round. He has also a
broad arched chest ; a strong voice, and the faculty of
retaining his breath for a long time without difficulty.
In general, there is a complete harmony in all his parts.
His senses are good, but not too delicate; his pulse is
slow and regular.

His stomach is excellent, his appetite good, and his
digestion easy. The joys of the table are to him of
importance ; they tune his mind to serenity, and his
soul partakes in the pleasure which they communicate.
He does not eat merely for the sake of eating ; but each
meal is an hour of daily festivity ; a kind of delight
attended with this advantage, in regard to others, that
it does not make him poorer, but richer. He eats
slowly, and has not too much thirst. Too great thirst
is always a sign of rapid self-consumption.

In general, he is serene, loquacious, active, suscepti-

138 ART OF PROLONGING LIFE.

ble of joy, love, and hope ; but insensible to the impres-
sions of hatred, anger, and avarice. His passions never
become too violent or destructive. If he ever gives
way to anger, he experiences rather an useful glow of
warmth, an artificial and gentle fever, without an over-
flowing of the bile. He is fond also of employment,
particularly calm meditation and agreeable speculations ;
is an optimist, a friend to nature and domestic felicity,
has no thirst after honors or riches, and banishes all
thoughts of to-morrow.

CHAPTER IX.

Examinations of various new methods for prolonging life. By vital
elixirs. Gold tinctures and wonder-working essences. By harden-
ing the organs. By rest and suspending for a time vital activity.
By guarding against consumption, and the external causes of
disease. By fast living. Account of the only methods possible
by which life can be prolonged. Proper union of the four princi-
pal indications. Increasing the vital power. Strengthening the
organs. Moderating vital consumption. Favouring restoration.
Modification of these methods, according to difference of constitu-
tion, temperament, age, and climate.

VARIOUS are the methods and plans which have been
proposed for the prolongation of life. The old super-
stitious, astrological, and fantastic methods we have
already examined and appreciated ; but there are
others, more modern, which appear to be founded on
juster principles of life and viial duration, and which
still deserve some inquiry before we proceed to estab-
lish that which alone is possible.

I think I have sufficiently proved, that the prolonga-
tion of life is possible, four different ways :
1st. By increasing the vital power itself.
2nd. By hardening the organs.
3rd. By retarding vital consumption.
4th. By facilitating and assisting restoration.
On each of these ideas have been founded plans and
methods, which in part are very plausible, and which

140 ART OF PROLONGING LIFE.

have been much commended ; but they are all deficient,
chiefly in this, that they regard only one object, and
neglect the rest.

Let us, therefore, examine and appreciate some of the
principal.

On the first idea, that of increasing the quantity of
the vital power, has been, in particular, founded, the
method of those who prepare and who use gold tinctures,
astralish salts, the philosopher's stone, and elixirs of
life. Electricity even, and animal magnetism, belong
in part to this class. All the Adepts, Rosicrucians, and
Consorts, and a multitude of people sensible in other
respects, are fully convinced that their first matter can
not only convert the rest of the metals into gold, but
continually supply the lamp of life with new oil. A
man, therefore, needs only take daily a small quantity
of such tinctures to recruit the vital power ; and thus,
according to their theory, we can never be exposed
to a want or a total loss of it. On this is founded the
history of the celebrated Gualdus, who by these helps
lived 300 years, and, as some firmly believe, is alive
still.

Those, however, who place confidence in these helps
are miserably deceived. The use of such medicines,
which are all hot and stimulating, increases naturally
vital sensation; and such people consider increase of
vital sensation as a real increase of the vital power,
without reflecting that a continual increase of the former
is, by irritation, the surest means of shortening life, and
in the following manner :

1st. These, in part, spirituous medicines act as strong
stimulants, increase the internal motion and intensive

life, consequently the self-consumption, and occasion a
more rapid wasting of the organs. Such is the case not
only with the coarser, but also with the more refined
substances of this kind. Even electricity, magnetism,
and the inspiring dephlogisticated air (oxygen gas),
which one certainly might believe to be the gentlest
method of instilling vital power, increase self-consump-
tion in a high degree. This may be very clearly per-
ceived in asthmatics, who are made to inspire such air.
Their vital sensation is thereby much exalted, but they
die sooner.

2d. These stimulating medicines, as they exalt vital
sensation and also sensibility, expose one more to exer-
tion of the powers ; to enjoyment, and to sensual gratifi-
cations, which some, however, particularly recommend ;
and by these means increase self-consumption.

3rd. They contract and desiccate, consequently make
the finer organs much sooner unfit for use, and bring
on premature old age, which they ought rather to
keep off.

And even supposing that our vital sensations required
to be so much exalted, neither alembics nor crucibles
are necessary for that purpose. Nature herself has
provided for us that most excellent spirit, wine, which
excels all those prepared by the art of man. If there
be anything in the world which one may call the prima
materia, that contains the spirit of the earth in an incor-
porated form, it is certainly this noble production ; and
yet we find that too liberal a use of it occasions a
speedier consumption, brings on old age, and evidently
shortens the duration of life.

But it is, indeed, foolish to endeavor to accumulate

142 ART OF PROLONGING LIFE.

the vital power in a concentrated form within the body,
and then to imagine that one has accomplished some-
thing great. Are opportunities of doing this, want-
ing ? It abounds in every thing near and around us.
All the nourishment we take, each mouthful of air
that we breathe, is filled with it. The principal point
is to preserve our organs in a state capable of absorb-
ing, receiving, and appropriating it. Let a lifeless
body be filled ever so much with vital drops, it will
not begin to revive, because it has no longer organs
to appropriate them. It is not the want of vital ac-
cession, but of vital capacity, which in the end makes
men unfit to live longer. But here Nature herself is
our guardian ; and, in this respect, all vital drops are
unnecessary.

On the second idea, strengthening the organs, a very
favorite system, that of hardening, \\&s also been founded.
It is therefore believed that the more the organs are
hardened, the longer they must naturally withstand
consumption and destruction.

But we have already seen what a great difference
there is between the mechanism of a thing and its vital
duration ; and that a certain degree only of solidity is
favorable to the latter, and that too much is highly
prejudicial. The essential character of life consists in
the Uninterrupted and free activity of all the organs,
and of the circulation of the juices ; and what can be
more destructive to these, and consequently to the dura-
tion of life, than too great hardness and rigidity ? Fish
certainly have the softest and most watery flesh ; yet
they far exceed, in vital duration, stronger and more
solid animals.

HARDENING THE ORGANS. 143

The favorite method of hardening, which consists in
endeavoring, by the continued use of the cold bath ; keep-
ing the body exposed, almost naked, to the keenest air,
and the most fatiguing exercise, to make one's self strong
and indestructible, produces no other effect than that our
organs become drier, tougher, and more rigid, conse-
quently much sooner unfit for use; and therefore, instead
of prolonging life, we bring on premature old age and
speedier dissolution.

There is, however, some truth, upon the whole, in this
method ; and it has proved unsuccessful, because people
united with it false ideas, and carried it too far. It is
not so much a hardening of the vessels as of the feel-
ing, that can contribute to the prolongation of life.
When one, therefore, employs the hardening method
so far as to make the vessels strong, but not hard or
stiff, so that their too great irritability, a principal
cause of speedy wasting, is blunted or removed, and
the body rendered thereby, at the same time, less sus-
ceptible of destructive influences, it may certainly, in
that case, be of some service in lengthening our exis-
tence.

The third idea, that of retarding vital consumption, is
highly captivating ; and has been adopted, in particular,
with great satisfaction, but very improperly employed,,
by those who are naturally much inclined to indolence
and ease. To waste the body by labor and exertion is,
to such people, unpleasant in itself; they are rejoiced,
therefore, to find it not only disagreeable, but also pre-
judicial, and to have, in indolence, a grand secret for
prolonging life, superior to all the arcana of Cagliostro
and St. Germain.

141 , ART OF PROLONGING LIFE.

Some have even gone still further, and in particular
Maupertuis, who conceived it might be possible, by a
complete suspension of vital activity, or an artificial
apparent death, to check self-consumption entirely, and
by such pauses, to preserve life for perhaps several
centuries. He supported his proposition on the life of
a chicken in the egg, and of insects in their state of
nymph and chrysalis, which, by the help of cold and
other means, whereby the animal is kept longer in its
deathlike sleep, can actually be prolonged. According
then to these principles, nothing is necessary but to ac-
quire the art of half-killing one. The same idea
occurred even to the great Franklin. While in France,
he received from America a quantity of Madeira wine,
which had been bottled in Virginia. In some of the
bottles he found a few dead flies, which he exposed to
the warm sun, in the month of July ; and in less than
three hours these apparently dead animals recovered
life, which had been so long suspended. At first they
appeared as if convulsed ; they then raised themselves
on their legs, washed their eyes with their fore feet,
dressed their wings with those behind, and began in a
little time to fly about. This acute philosopher pro-
posed, therefore, the following question : " Since, by
such a complete suspension of all internal as well as
external consumption, it is possible to produce a pause
of life, and at the same time to preserve the vital prin-
ciple, might not such a process be employed in regard
to man ? And if that be the case," adds he, like a true
patriot, "I can imagine no greater pleasure than to
cause myself to be immersed, along with a few good
iriends, in Madeira wine, and to be again called to life

PERIODICAL SUSPENSION OF LIFE. 145

at the end of fifty or more years, by the genial solar
rays of my native country, only that I may see what
improvement the State has made, and what changes
time has brought along with it."

This proposal, however, vanishes again into nothing
when we consider the real essence and object of human
life. What is meant by the life of man ? Not, indeed,
mere eating drinking, and sleeping, else it would agree
perfectly with the life of a swine, to which Cicero could
give no other name than a preventive of corruption.
The life of man has a higher destination action,
business, and enjoyment. It is not enough that it be
present, it must expand, and bring to perfection those
divine seeds which exist within him ; it must give hap-
piness to himself and to others. Man must not merely
fill up a gap in the creation, he must be the lord, the
ruler, and the benefactor of it. Can one say of a man.
that he lives, when he spins out life amidst sleep, indo-
lence, or apparent death ? But what is still more, we
find here also a new proof in how inseparable a manner
the moral object is interwoven with his physical appoint-
rnent arid destination, and how promoting the one con-
duces to improve the other. Such an unmanly life, as
it may be properly called, would contribute directly not
to prolong, but to shorten human existence, and in two
ways :

1st. Human life is composed of so tender and delicate
organs that they very readily become unfit for use by
rest and inactivity. It is only action and exercise
which make them useful and durable. Rest and want
of exercise are their most deadly poison.

2nd. We have already seen that not merely lessening
10

146 ART OF PROLONGING LIFE.

consumption, but promoting restoration also, in a suf-
ficient degree, is necessary for the prolongation of life.
But two operations are here requisite : first, perfect
assimilation of what is useful; and, secondly, excre-
tion of what is hurtful. The latter can never take
place without proper activity and motion. What would
be the consequence of a prolongation of life by means
of rest and indolence ? The body would be consumed
very little or not at all, and yet restoration would be
carried on. A most destructive plethora must thence
arise, because the body always receives and never
throws off. And, what is still worse, universal corrup-
tion, with its train of evils, acrid humors, disease, etc.,
must gain the upper hand, as the secretion of what is
prejudicial has been stopped. It is very natural, there-
fore, to suppose that such a body would be much sooner
destroyed, as experience teaches us.

3d. With regard to the prolongation of life by a sus-
pension of the vital activity, during a temporal state of
apparent death, I shall, in the last place, observe, that
this idea has been founded on the example of insects,
tortoises, and other animals, which, as we have before
seen, can, by such a deathlike sleep, be preserved a
hundred years and more, and, consequently, far beyond
the natural term of their existence.

But, in making such proposals, people do not reflect
that all those experiments were tried upon very imper-
fect animals, among which the transition from their
natural half-animated state to actual torpor is much less
abrupt than it would be among men, who possess the
highest degree of vital perfection. And one, in particu-
lar, must here observe the important difference made

PERIODICAL SUSPENSION OP LIFE. 147

by the business of respiration. All these animals have
naturally less need of breathing ; and warmth is less
necessary to them in order to retain life. Man, on the
other hand, requires, for the preservation of his life, a
continual accession of heat and spiritual powers ; in
short, of the pabulum vitce* which exists in the atmos-
phere. Such a total suspension of breathing would, by
an entire loss of internal heat, soon become mortal.
The more perfect agency of the soul is so interwoven
with the organization of man, that its influence could
not be stopped so long without causing the death and
destruction of the more delicate organs which belong
to it.

Others have attempted to prolong life by endeavoring
to avoid or remove the causes of disease, such as heat
and cold, certain kinds of food and drink, etc. But this
method is attended with one disadvantage, which is,
that we are not able to guard against all these evils ;
and that we are, therefore, rendered much more sensi-
ble of those which affect us. The preventing of con-
sumption externally may also be here included. In
warm countries, where the heat of the atmosphere
keeps the skin always open, and makes the evaporation
of the component parts of our bodies far more constant,
people find some benefit from rubbing the skin continu-
ally with ointments and oil, which stop up the pores,
and prevent the more watery and volatile particles
from flying off in perspiration. By this process one
experiences a real sensation of strengthening ; and, in
such climates, it appears to be necessary to check too

148 ART OF PROLONGING LIFE.

speedy consumption by profuse evaporation. But it is
certain that it is in warm climates only that it can be
employed. In our climate, where the atmosphere it-
self acts as a medium to shut up the pores of the skin,
we have more need of promoting perspiration than of
preventing it.

I must now say a few words respecting an entirely
new experiment for prolonging vital existence, which
consists merely in increasing intensive life. On this
principle the duration of life is determined, not by num-
ber of days, but by the sum of its use or enjoyment ;
and it is believed that if one, within a certain period,
has had twice as much action and enjoyment as another,
he has lived as much as the other in double the time.
However much I respect this method in itself, if it con-
sist in laudable exertion, and be the consequence of a
mind fertile in action ; and though I am fully convinced
that, considering the uncertainty of our life, it presents
an idea highly captivating ; I must confess, that it will
never obtain its object, and that the principle of it
appears to be altogether false. As this opinion has
found so many advocates, I hope I shall be permitted
to analyze it a little more accurately, and to explain
the grounds of my assertion.

All the operations of nature require not only energy
or intensive life, but also extension or time. Let fruit
receive twice as much heat and nourishment as it has
in its natural state, and in half the time it will attain to
apparent ripeness ; but certainly not to that degree of
perfection which the same fruit acquires in its natural
state, with half the intensive activity, in double the time.

The case is the same with the life of man. We must

INCREASED INTENSIVE LIFE. 149

consider it as a whole compounded of various effects ;
as a grand ripening process, the object of which is to
give the utmost expansion and perfection possible to
human nature, and to make it fill up that point which
it holds in the creation. Now ripening and maturity
are the produce only of time and experience ; and it is,
therefore, impossible that a man who has lived thirty
years, though in that time his action and labour may
have been doubled, should have attained to the same
perfection and maturity that are acquired in a period
of sixty years. Besides, he was perhaps destined to
be useful in the course of his life to two or three gen-
erations ; but his prematurity hurries him off before
he has seen the end of the first. He accomplishes,
then, neither in regard to himself nor to others, Jie
object and destination of complete life ; interrupts the
course of his days ; and remains a more refined suicide.

In a still worse point of view appear those who en-
deavour to prolong life by concentrating its enjoyments.
By these means they may be wasted much sooner ; and
what is worst of all, they are often punished for their
folly, because they must lead a life merely intensive
without any extension ; that is, they must become a
burden to themselves and to others, or rather they exist
longer than they live.

The true art of prolonging human life consists in
uniting properly, and employing, the before-mentioned
four principles, or indications, as they are termed by
physicians ; but in such a manner that none of them be
sacrificed to the rest, and that one never forget that the
question is concerning the life of man, which, to deserve
that name, must consist not merely in existing, but in

150 ART OF PROLONGING LIFE.

business and enjoyment, and in fulfilling the end of his
destination. I shall here take a short view of the whole
method.

I. The sum or fund of the vital power must he suffi-
ciently supplied and nourished ; yet never to such a
degree as to occasion too violent exertion of it, but
only so far as may be necessary for it to perform the
external and internal functions with proper ease, strength,
and duration, and to give the component parts and
juices that organic character which is requisite for
their destination, and for guarding against chemical cor-
ruption. This may be done with the greatest cer-
tainty,

1st. By sound and powerful generation.

2d. By pure and wholesome vital nourishment or
accession from without ; also pure atmospheric air ;
and good, fresh, well-digested food and drink.

3d. By a sound and useful state of those organs by
which every thing added to us from without must be
assimilated before it can do us good. These essential
organs are the lungs, stomach, and skin ; on the pre-
serving of which in a sound state, vital nourishment
depends in a very particular manner.

4th. By an uniform diffusion of the power throughout
the whole body. Every part, every intestine, every
point of our bodies, must obtain such a quantity of the
vital power as may be necessary to enable it to dis-
charge its functions properly. Does any part acquire
too little, a weakness of it is the consequence ; if it ac-
quire too much, the consequences are too violent motion,
irritation, accumulations of it ; and then that harmony,
the grand pillar of sound life, is, at any rate, always

TONE AND STRENGTH OF ORGANS. 151

destroyed. This uniform distribution of the power may
be promoted, in particular, by the uniform use and ex-
ercise of each part and each organ of the body ; by
bodily motion ; proper gymnastic exercises ; the tepid
bath, and friction.

II. A sufficient degree of solidity or hardness must be
given to the organs or corporeal matter ; but not such as
to render them actually stiff and rigid, which, instead of
being beneficial to the body, would be hurtful to it.

The hardness to which I here allude is of two kinds :
increased binding and cohesion of the component parts,
as well as physical solidity of the vessels ; and next,
hardening the sensation against noxious and morbid
impressions.

Sufficient solidity or cohesion of the vessels, which
physicians call tone, acts in the following manner, in
regard to the prolongation of life :

First, as the cohesion of our component parts is
thereby increased, they cannot be so speedily wasted,
destroyed, and separated by the vital process ; conse-
quently the change of the component parts is not so
rapid : it is not necessary that they should be so often
renewed ; and the whole intensive life is more slow,
which is always an advantage in regard to its extension
and duration. For the better illustration of this sub-
ject, I shall here only compare the life of a child with
that of a man. In the former, the power of cohesion,
the solidity of the vessels are much less ; the connection
of the component parts is weaker and more lax, it
wastes away therefore much speedier ; the change of
its component parts is more rapid ; it must eat more,
and much oftener ; it must sleep longer, and more fre-

152 ART OF PROLONGING LIFE.

quently, to renew what has been lost ; and the blood
must circulate with far greater velocity ; in a word, its
intensive life and self-consumption are much stronger
than in a man who has vessels more solid.

Secondly, as the organs are thereby, in reality, first
strengthened. The vital power alone supplies no
strength. To produce what we call strength of the
organs, and also of the whole system, a sufficient degree
of the simple power of cohesion must be combined with
the vital power. This likewise will appear in the
clearest manner, from the comparison of a child with a
man. A child is far more abundant in vital power,
irritability, tendency to growth, and the power of repro-
duction, than a man ; yet this body, so rich in life, has
less strength than that of a man, merely because the
cohesion of the vessels in the child is weaker and more
loose.

Lastly, because the too great morbific or irregular
irritability, sensibility, and general delicacy of the ves-
sels, are regulated, moderaied, kept wiihin proper
bounds, and preserved in good order, by a sufficient
mixture- of the power of cohesion ; and by these means
the too strong irritation and consumption of the powi r
by life is lessened ; the extension and duration of life
are, consequently, increased ; and this advantage also
is gained, that external noxious causes of irritation act
less rapidly, and with less violence.

By a stronger cohesion, the capacity of the matter
for receiving vital power seems also to be heightened;
at any rate, a stronger connection of the vital pow( r
with the matter is effected.

The means by which this increased solidity and co-

TONE AND STRENGTH OF ORGANS. 153

Lesion of the vessels can be produced, are as fol-
lows :

1st. Exercise, and the use of the muscular powers
and vessels, both voluntary, by voluntary muscular mo-
tion, as well as involuntary, for example, of the stomach
and intestines by suitable stimulants, such as food some-
what solid or hard ; and of the bloodvessels, by some-
what stimulating medicines. On each movement of a
vessel, it contracts ; that is to say, its component parts
approach each other; and if this be done often, its
cohesion or tone will be increased. One only must be
extremely cautious not to occasion too strong an irrita-
tion, else consumption might be too much increased,
and the consequences become dangerous.

2nd. The use of gelatinous, corroborating nourish-
ment, impregnated with ferruginous particles, wh'ch
increase this power ; and to avoid too many watery
substances, which might lessen it.

3rd. To promote moderate perspiration by friction,
motion, etc.

4th. A cool temperature of the atmosphere, and of
the whole system, a point of the utmost importance.
Though cold is not a positive strengthener of the vital
power, yet it increases and strengthens the weak cohe-
sive power or tone ; corrects too strong exertion of the
vital power, as well as prevents it from being exhausted ;
and, in this manner, can be a negative strengthener of
the vital power itself. Warmth, on the other hand,
weakens, partly by relaxing the cohesion, and partly
by exhausting the vital power.

1 must, however, repeat, in regard to all these means,
cold, strong substantial nourishment, motion, etc., that

154 ART OF PROLONGING LIFE.

one must not carry them too far, lest, instead of the
requisite solidity, too great stiffness or rigidity of the
vessels should be produced.

The sensation will be best hardened against the
causes of disease, if one accustoms oneself to such im-
pressions, and to sudden changes.

III. The vital consumption must be so lessened, or
moderated, that it may not be attended with too speedy
wasting of the powers and the organs.

The whole vital operation, as has been already shown,
consists in action, exertion of the vital power ; and is
consequently connected, in an inseparable manner, with
consumption and wasting of that power. This is the
case, not only in regard to the voluntary, but also the
involuntary, functions ; not only in the external, but
also the internal, vital operations ; for they are sup-
ported by continual irritation and reaction. Neither of
these, therefore, must be overstrained, if we are desir-
ous of preventing consumption.

Among these I reckon, in a particular manner, the
following irritations and exertions of power :

1st. Straining the system of the heart and blood,
with too great quickening of the circulation ; that is, by
too stimulating, hot nourishment, affections, and feverish
disorders. Great wine and brandy drinkers, as well as
passionate people, have a quick accelerated pulse, and
keep themselves in an incessant artificial fever, by which
they are as much wasted and consumed as they would
be by a real fever.

2d. Too strong or continued straining of the powers
of thought ; by which, not only the vital power is ex-
hausted, but the stomach and system of digestion are

RESTRICTED VITAL CONSUMPTION. 155

injured, and, consequently, the most important means
of restoration are weakened.

3d. Too abundant and too strong irritation and grat-
ification of the animal passions. These tend as much
to hasten vital consumption, as straining the powers of
thought.

4th. Too violent and too long continued muscular
motion. Very great excess, however, is necessary
before this can be hurtful.

5th. All strong or long continued excretions, such as
perspiration, diarrhoea, catarrh, cough, loss of blood,
etc. These exhaust not only the power, but also the
matter, and tend to corrupt the quality of the latter.

6th. All too violent or too long continued causes of
irritation acting upon us, by which the power is always
exhausted. The more irritable a life is, the quicker it
will pass away. To these belong too strong or too
incessant irritation of the organs of the mind and sensa-
tion ; passions, excess in wine, brandy, spiceries, and
seasoning of food. Frequent overloading the stomach
may be included in the same class ; especially as it for
the most part renders necessary the use of evacuants
and purgatives, which, as they weaken, are also preju-
dicial.

7th. Diseases with highly increased irritation, parti-
cularly such as are feverish.

8th. Heat, when it acts upon us too incessantly and
with too much strength. Keeping the body too warm,
therefore, from infancy, is one of the greatest means to
hasten consumption, and to shorten the duration of
life.

9th. In the last place, too great a degree of irrita-

156 ART OF PROLONGING LIFE.

bility and sensibility in the vessels deserves also to be
inserted in this rubric. The greater these are, the easier
can any stimulus, even the smallest, excite violent irrita-
tion, exertion of power, and consequently occasion a waste
of that power. A man with this faulty constitution is
sensible of a great many impressions which have no
effect on common men, and is doubly affected even by
the most usual accidents of life. His intensive life, of
course, is infinitely stronger ; but his vital consumption
must be greatly accelerated. Every thing, therefore,
which can increase irritability, either moral or physical,
may be reckoned to belong to those means which hasten
consumption.

IV. Restoration of the lost powers and matter must
be effected easily and completely. For this purpose the
following things are necessary :

1st. Soundness, vigor, and activity of those organs
by which the restorative particles must pass into our
bodies. This process is, in part, continual and perma-
nent, as through the lungs ; and partly periodical, as
through the stomach. To these organs belong the
lungs, the skin, the stomach, and the intestines. That
restoration may be performed well, these parts must be
thoroughly sound, fit for use, and active. They are
consequently of the utmost importance in prolonging
life

2d. Soundness, activity, and vigor of the innumera-
ble vessels, by which the component parts received
into our bodies must be assimilated, rendered homoge-
neous, be brought to perfection, and ennobled. This is
first, and in a particular manner the function of the
absorbing or lacteal system, with its multitude of

RESTORATION OF VITAL POWER. 157

glands ; and, secondly, of circulation, or the system of
the blood, by which organic ennobling is completed. I
consider the absorbing system, therefore, as one of the
grand means of restoration. In this respect we must,
above all things, direct our attention to infancy ; for the
first nourishment in the tenderest state of childhood,
the treatment, during the first year of life, determine,
for the most part, the condition of this system, as it too
often happens that it is destroyed in the beginning, by
weak, corrupted, viscid nourishment, and impurities ;
and an essential foundation is thus laid for a short life.

3d. A sound state of the nourishment and matter
from which we are restored. Our food and drink must
be pure, that is, free from corrupted particles ; abun-
dant in nutritive principles ; stimulating in a certain
degree, for that quality is necessary to promote proper
digestion and the whole vital operation, but combined,
at the same time, with a sufficient quantity of water or
of fluids. The last is ah important circumstance, but
often neglected. Water, if it be not nourishment of
itself, (though this, by the instance of fishes, worms,
etc., who may be fed for a long time with water alone,
seems highly probable,) is at any rate indispensably
necessary for the business of restoration and nourish-
ment ; first, because it must be the vehicle for the
proper nutritive substances, in order that they may be
sufficiently diifused from the intestines to every point
of the body ; and, secondly, because this vehicle is abso-
lutely necessary to produce sufficient secretion and
evacuation of what is corrupted, and consequently for
the purification of the body.

4th. A healthful and proper state of the atmosphere

158 ART 9F PROLONGING LIFE.

in which and on which we live. The air is our pecu-
liar element ; and, in two points of view, an important
medium of restoration. First, because it communicates
to us two of the most spiritual and most necessary com-
ponent parts of life, oxygen and heat ; and, secondly,
because it is the most important vehicle for attracting
from us and absorbing our component particles which
have become corrupted. It is the principal medium for
this continual exchange of the finer component parts.
The far most considerable and important of our excre-
tions are gaseous ; that is to say, the matter must be
converted into vapour in order to be expelled. To
these belong all excretions of the superficies of our
bodies, the skin, and the lungs. This evaporation de-
pends not merely on the power and activity of the
vessels of respiration, but on the quality of the air
which they draw in. The more it is already loaded
with component parts, the less new substance can it re-
ceive ; and, therefore, moist air checks perspiration.
From these principles we may deduce the following
conclusions : The atmosphere in which we live must
contain a sufficient quantity of vital air, but not too
much, else it might stimulate too violently and hasten
vital consumption. It must likewise contain as few
foreign component parts dissolved in it as possible : it
must also be neither moist, nor rendered impure by
earthy, .vegetable, or animal particles :* its temperature

* In defining corrupted air an accurate distinction should be
made between impure air and saturated air, which in general are
confounded. Corruption of the air may consist either in too small
a quantity of oxygen gas, or in the chemical mixture ; and air so
corrupted may be called impure air, in opposition to pure vital

RESTORATION OF VITAL POWER. 159

must be neither too warm nor too cold ; for, in the
former case, it exhausts and weakens the power, in the
latter makes the vessels too stiff and rigid : and it must
neither in its temperature, mixture, nor pressure, be
subject to too rapid changes ; for it is a law, fully con-
firmed by experience, that uniformity in the atmosphere
and climate is uncommonly favourable to long life.

5th. A free passage and active organs to promote
secretion and evacuation of the corrupted component
particles. Our life consists of a continual change of
component parts. Were not those which have been
Exhausted and rendered useless continually separated
and expelled, it would be impossible that we could ap-
propriate new ones in sufficient quantity ; and, what is
still worse, the new addition, by being mixed with those
particles kept back, would itself acquire the character
of corruption. Hence, the so-called acridity, viscosity,
impurity, and putrefaction of the juices, or rather of the
whole matter of the body. Restoration, therefore, is by
bad secretion prevented two ways ; partly in the quan-
tity and partly in the quality. The organs on which
this secretion and purifying of the body principally de-
pend are the skin, the kidneys, the liver, the intestines,
and the lungs. Of these the first is the most important,
as it is calculated that two thirds of the component parts
which have been used, evaporate by the insensible per-
spiration of the skin.

6th. To stimulate the senses in an agreeable manner,
and with moderation. Man, in consequence of the su-

air ; or it may be corrupted by foreign component parts received
into it, and then it is called saturated.

160 ART OF PROLONGING LIFE.

periority of his organization, as has been already shown,
and of his higher physical perfection, is susceptible of
more refined as well as more exalted impressions ; and,
consequently, they must have a greater influence on the
physical state of his life than on animals. By these
means there is opened for him a new source of restora-
tion, which is denied to animals ; the enjoyment and
stimulus of sensual pleasure, when not carried to too
great a length.

7th. Putting the mind in an agreeable frame ; joyful
and moderate affections ; a succession of new, grand
ideas ; creating, combining, and varying them. These
more exalted pleasures, exclusively peculiar to man,
belong to this catalogue of the means which contribute
to prolong his existence. Hope, love, and joy are there-
fore happy affections ; and there is nothing which tends
with so much certainty and so generally to preserve
life and health as cheerfulness and serenity of mind.
Such a disposition keeps the vital power in a proper
uniform state, promotes circulation and digestion, and
assists, in a very powerful manner, the function of in-
sensible perspiration. Happy, therefore, even in a
physical point of view, is that man on whom Heaven
has bestowed a contented and serene mind, or who, by
improving and cultivating his moral faculties, has been
able to procure that blessing. He has within himself
the noblest and purest balsam of life.

The principles here laid down contain the funda-
mental rules on which every rational general plan for
prolonging life must be founded. But what is necessary
in regard to every dietetic and medicinal precept is

PRINCIPLES MODIFYING RESTORATION. 161

necessary here, that, in applying them, regard must be
had to special cases ; and that, therefore, they must be
more accurately modified and determined.

The following circumstances, in particular, are to be
attended to in the application of them :

Difference of constitution, in the subjects, in regard to
their simple component parts and vessels. The drier,
the harder, and more rigid the state of the body natu-
rally is, the less need there will be for employing the
means of the second indication, that is, a proper hard-
ening ; but the more relaxed .the vessels are by nature,
the contrary must be the case.

Further, the different innate temperaments, under
which I comprehend the different degrees of irritability,
and their relation to the powers of the soul. The more
a subject inclines to the phlegmatic temperament, the
more and the stronger irritants may be employed. A
degree of irritation, which in a sanguine temperament
would waste and exhaust, is here beneficial ; necessary
to promote a sufficient degree of vital operation, and a
means of restoration. The case is the same with the
melancholic temperament: it requires more irritation,
but variegated, of a pleasant nature, and not too vio-
lent. The more the sanguine temperament prevails,
the more cautiously and moderately must all stimulants
as well physical as moral be employed ; and in this
respect, the choleric, where the smallest stimulus may
often produce the most violent exertion arid rapid
wasting, requires the greatest attention.

The periods of life. Children and young people
have far more vital power and irritability ; their struc-
ture is less solid and the change of their component
11

162 ART OF PROLONGING LIFE.

parts is more rapid. Much less irritation must, there-
fore, be here given, because a small irritation excites
strong reaction. More regard must be proportionally
paid to restoration and hardening. In old age, on the
other hand, every thing called irritation may be em-
ployed in a stronger degree. What in infancy would
be consumption, is here restoration. Milk is wine for
children; wine is milk for old people. Old age requires,
therefore, on account of the great rigidity connected
with it, not an increase of that quality by the second
indication, but a lessening of it by means of emollients
and moistening things, meat-broths, strong soups, and
the tepid bath.

Lastly, Climate, also, makes some difference. The
more southern it is, the greater is the irritability ; the
stronger continual irritation is, the more rapid will the
stream of life flow, and the shorter will be its duration.
Great attention is here necessary that this exhausting
of the power by too strong irritation, may not be accele-
rated. In a northern climate, on the other hand, where
the temperature being cooler concentrates the power
more, and keeps it together, this is much less to be ap-
prehended.

ART OF PROLONGING LIFE.

PART THE SECOND.

I NOW proceed to the most important part of this
Treatise, the Practical Art of Prolonging Life ; and I
can now make known with confidence, and on good
grounds, those means by which alone prolongation of it
is possible. If they are not so specious, so boasting,
and so mysterious as those commonly recommended,
they have this advantage, that they may be everywhere
found without expense, nay, that they in part lie within
ourselves ; that they are perfectly consistent with reason,
as well as experience ; and that they prolong, not
merely life, but also the enjoyment of it. In a word,
according to my idea, they deserve the name of univer-
sal remedies, much more than all the panaceas of
quackery and imposture.

We are continually surrounded by the friends and
the enemies of life. He who keeps company with its
friends, will become old ; but he who prefers its ene-
mies, will shorten his existence. It might be expected
of every prudent man, that he would prefer the former,
and be always on his guard against the latter ; but it is

164 MEANS WHICH SHORTEN LIFE.

an unfortunate circumstance that these enemies of life
are not all public and known. They, in part, carry on
their attacks secretly and imperceptibly; so that some
of them assume the mask of life's best friends. It is,
therefore, difficult to discover them ; and some we even
harbor within our own bosoms.

The principal part of this Art, then, will consist in
being able to distinguish our friends from our enemies,
and in learning to guard against the latter. In other
words, the Art of prolonging Life may be divided into
two parts :

I. Guarding against the enemies of life, and those

means which shorten it.

II. The knowledge and use of those means which
tend to prolong it.

MEANS WHICH SHORTEN LIFE.

ACCORDING to the principles before laid down, the
Only grounds on which the duration of life depends, it
will not be difficult to determine in how many different
ways it may be shortened.

I 1st. Every thing must shorten it which lessens the

sum of the vital powers ;

2nd. Every thing that takes from the organs of life
their duration and renders them unfit for use ;
3rd. Every thing that hastens vital consumption ;
4th. And every thing that prevents restoration.

MEANS WHICH SHORTEN LIFE. 165

Every thing that shortens life may be comprehended
in these four classes; and we have now a standard by
which the greater or less mischief, occasioned by their
influence, can be determined and appreciated. The
more these four properties are in any thing united, the
more dangerous and hostile will it be to our vital dura-
tion ; and the fewer it contains, it will be less so. Nay,
there are mixed substances which present as it were
two sides, one friendly, and another hostile ; that is to
say, which possess one of the above properties, but at
the same time are more favorable and beneficial to us
than hurtful. These may form one peculiar class, but
we shall here, according to their prevailing quality,
assign them a place, either among those things which
are friendly, or those which are hostile.

Between those things which shorten life, there is a
difference still more important. Some act slowly, suc-
cessively, and often very imperceptibly. Others, on the
contrary, violently as well as suddenly ; and these may
be rather named the destroyers of life. To these belong
certain diseases, and the various kinds of violent death,
as they are properly called. The latter, in general,
are much more dreaded than the former, because their
effects are more perceptible and more terrible : but I
can assure my readers, that they are at bottom much
less dangerous than these secret enemies; for they are
so open that people can be much sooner on their guard
against them than against the former, which carry on
their destructive approaches in private, and daily steal
from us some part of life without our perceiving it,
though the loss in the end may amount to a sum truly
alarming.

166 MEANS WHICH SHORTEN LIFE.

I must here make one melancholy remark, which is,
that the enemies of our life have, in modern times,
dreadfully increased ; and that the degree of civilization,
luxury, refinement, and deviation from nature, in which
we at present live, by so highly exalting our intensive
life, tends also to shorten, in the same proportion, our
existence. We shall find, on close examination, that
men appear, as it were, to have anxiously studied how
they might deprive each other of life secretly and im-
perceptibly, and often in the most ingenious manner
possible. Much more precaution and attention are,
therefore, now necessary in order to secure ourselves
from danger.

CHAPTER I.

\

Delicate nursing and treatment in infancy.

THERE is no surer method of rendering the vital
thread of a being from its origin short and perishable,
than by giving it, during the first years of life, which
may be considered as a continued generation and ex-
pansion, a very warm, tender, and delicate education ;
that is, by guarding it from every breath of cool air ;
burying it for at least a year among pillows and blankets,
and keeping it like a chicken in a real state of hatching;
not omitting, at the same time, to stuff it immoderately
with food ; and, by coffee, chocolate, wine, spice, and
such like things, (which for children are nothing else
than poison,) to irritate it beyond measure, and to ren-
der its whole vital activity too strong and violent.
By these means its internal consumption is from its
birth so accelerated, its intensive life is so early exalted,
and its organs are rendered so weak, tender, and sensi-
ble, that one may assert that, through two years' treat-
ment of this kind, an innate vital capacity of sixty
years may be reduced one half; nay, as experience un-
fortunately shows, to much less, without reckoning those
evil accidents and diseases which may besides be the
consequence. The premature expansion of our organs
and powers is by nothing so much hastened as by
such a forced education ; and we have before proved

168 MEANS WHICH SHORTEN LIFE.

what an intimate connection there is between rapid or
slow expansion, and a longer and shorter duration of
life in general. Speedy ripening carries always along
with it* speedy destruction. This, certainly, is one
great cause of the dreadful mortality which prevails
among children. But men overlook those causes which
lie nearest to them, and assume rather the most absurd,
in order that their minds may be at rest, and that they
may have as little to do as possible.

# One of the most remarkable instances of the prematurity of
nature was Louis II., King of Hungary. He was born so long
before the time that he had no skin. In his second year he was
crowned ; in his tenth he succeeded ; in his fourteenth he had a
complete beard ; in his fifteenth he married ; in his eighteenth he
had gray hair, and in his twentieth he died.

CHAPTER II.

Physical excess in youth.

"As youth is the period of growth, of forming and
collecting the powers of the future man, every kind of
excess calculated to weaken or exhaust the vital powers
should be carefully guarded against. There are certain
active properties which belong to this period, such as
muscular motion, which can hardly be carried beyond
the bounds of health. But the excesses most to be
dreaded are those which spring from a too early antici-
pation of the future man, in which the imagination and
the feelings play a conspicuous part. Youth, it cannot
be too often repeated, is the time for storing strength,
both physical and moral ; and every act which can in
any way impede or frustrate this all-wise intention of
Nature, will tend to lay the foundation of a weak and
imperfect body, and shorten the days of its possessor.
Among the passions of the future man, which at this
period should be strictly restrained, is that of physical
love; for none wars so completely against the princi-
ples which have been already laid down as the most
conducive to long life ; no excess so thoroughly lessens
the sum of the vital power; none so much weakens and
softens the organs of life ; none is more active in hasten-
ing vital consumption; and none so totally prohibits
restoration.

170 MEANS WHICH SHORTEN LIFE.

I might, if it were necessary, draw a painful, nay, a
frightful picture, of the results of these melancholy ex-
cesses ; but I refrain, in the hope that this simple
caution will be sufficient. To my youthful readers I
will simply say, Be wise in time. Experience may
appear a harsh, but, nevertheless, she is a just mon-
itor." EDITOR.

CHAPTER III.

Overstrained exertion of the mental faculties.

MENTAL as well as bodily excess, is attended with
destructive consequences ; and it is worthy of remark,
that too great exertion of the mental faculties, and the
waste of the vital power connected with it, produce on
the health and vital duration almost the same effects
as a waste of the physical powers loss of the power
of digestion, depression, dejection, weakness of the
nerves, consumption, and premature death.

Much, however, depends here on the difference of
structure and constitution ; and those who have natu-
rally a stronger and more active organization of soul,
must suffer less from such exertion than those who are
destitute of that advantage. Those, therefore, are most
affected by it, who, with a moderate structure of mind,
attempt to force it beyond its powers ; and that exces-
sive mental exertion which we make involuntarily, and
without pleasure in the object of it, will hence weaken
us most.

But it may here be asked, What is meant by excess
in mental exertion ? This, in general, is as difficult to
be defined as excess in eating and drinking ; because
the whole depends on the difference in the capacity and
state of the mental powers, and these are as different

172 MEANS WHICH SHORTEN LIFE.

as the powers of digestion. That may be excess of
mental exertion for one, which is not so for another,
endowed with stronger faculties. The circumstances,
also, under which that function is exercised, make a
very essential difference. I shall, therefore, define
more accurately what is to be understood by excess in
the function of thinking.

1st. When one, while employed in abstruse thought,
neglects too much the body. Every irregular exertion
of our powers is hurtful ; and as a man is infinitely
more weakened when he exercises his thought without
attending to bodily exercise, it is equally certain that
those can undergo more mental labor, and with much
less injury to their health, who, in the mean time, give
to the body suitable and periodical exercise.

2d. When one thinks too incessantly on the same
subject. The same law prevails here as in regard to
muscular motion. When one moves the arm continu-
ally in the same direction, one, in a quarter of an hour,
will become more fatigued than if the limb had been
moved two hours in various directions. Nothing ex-
hausts so much as uniformity in the pursuit and em-
ployment of the mental powers ; and Boerhaave tells
us that after having bestowed intense study, for a few
days and nights, on the same object, he fell suddenly
into such a state of lassitude and relaxation, that he lay
some time in an insensible and deathlike condition. A
proper change of objects is, therefore, the first rule in
order to study without injury to the health, and even
to accomplish more work upon the whole. I am ac-
quainted with great and intense thinkers, mathemati-
cians, and philosophers, who, at an advanced period of

OVERSTRAINED MENTAL EXERTION. 173

life, are still happy and contented; but I know also
that they have made this variety a law, and that they
always divide their time between these abstract studies
and reading history, agreeable poetry, travels, and
works of natural history. It is of great benefit, in this
respect, to unite always a practical with a speculative
life.

3d. When one employs the mind on too abstract or
difficult subjects ; as for example, problems of the
higher mathematics and metaphysics. The object
makes a very essential difference. The more abstract
it is, and the more it obliges one to disengage one's self
from the sensual world, and, as it were, to insulate the
mind separated from the body, the most unnatural state,
without doubt, that can possibly be, the more weaken-
ing and overstraining is its effect. Half an hour of
such abstraction exhausts more than a whole day em-
ployed in translation. But here, also, a great deal is
relative. Many are born for such labor, and have
those powers and that frame of mind which it requires ;
while on the other hand, many are destitute of both,
and yet endeavor to force them. It appears to me very
singular that, when it is requisite to raise up a corpo-
real burden, people always first try it by their strength,
to discover whether it be not too heavy for them ; but
in regard to a mental burden, never consult their powers
to know whether they are sufficient to sustain it. How
many have I seen miserable and enervated, merely
because they attempted to dive to the depths of philoso-
phy without having philosophical heads ! Must every
man, then, be a philosopher by profession, as seems to

174 MEANS WHICH SHORTEN LIFE.

be the mode at present ? In my opinion, a particular
organization is necessary for that purpose ; and it may
be left to the chosen few to investigate and unfold the
secrets of philosophy ; as to others, let them be contented
with acting and living like philosophers.

4th. I consider it also as excess, when one labors
always in creating and never in enjoying what has
been created by others. The labor of the mind may
be divided into two parts : the creative, which produces
of itself and gives birth to new ideas ; and the recipient,
or passive, which merely receives and enjoys foreign
ideas, as, for example, by reading or hearing others.
The former is by far the most exhausting ; and one
ought, therefore, to vary them, and to enjoy them in
turns.

oth. When one begins to overstrain the mind too
early in infancy. At this period a small exertion is
highly prejudicial. Before the age of seven, all men-
tal labor is an unnatural state, and attended with con-
sequences as fatal to the body as the most exhausting
excess.

Gth. When one studies invita Minerva, that is ap-
plies to subjects on which one labors involuntarily, and
not con amore. The more inclination one has for any
kind of mental enjoyment, exertion will be the less
hurtful. More caution, therefore, is necessary in the
choice of studies ; and wretched must those be who
neglect an object of so much importance.

7th. When one stimulates, strengthens, or prolongs
mental exertion by artificial means. People employ
commonly, for this purpose, wine, coffee, or snuff; and

OVERSTRAINED MENTAL EXERTION. 175

though these artificial helps of thought are in general
not to be approved, because they always exhaust
doubly, it must, however, be confessed, that, at those
times when the labor of the mind does not depend upon
the will, but on periods and hours, they cannot alto-
gether be dispensed with ; and on such occasions, a
dish of coffee, a pipe of tobacco, or a pinch of snuff,
may be the most sufferable. But let people be on their
guard against excess ; because an abuse of them must
increase, in an incredible degree, the mischiefs of men-
tal exertion.

8th. When one overstrains the mind during the time
of digestion. This occasions double injury : one weak-
ens one's self more, as more exertion is then necessary
for thinking, and interrupts at the same time the impor-
tant function of digestion.

9th. When one employs, in mental labor, that time
which ought to be devoted to sleep ; a custom highly
prejudicial to life, and of which I shall speak more ex-
pressly when I come to treat on sleep.

10th. When one unites study with hurtful external
circumstances ; and of these there are two in particu-
lar, sitting in a bent posture, and confined air ; which
are often more destructive in their consequences than
intense thinking itself. People, therefore, ought to
accustom themselves to study lying, standing, walking,
or riding on a hobby ; not always in the closet, but
sometimes in the open air ; and they will then suffer
much less from those diseases which are so incident
to men of letters. The ancient philosophers undoubt-
edly studied as much as the modern literati ; and yet

176 MEANS WHICH SHORTEN LIFE.

never suffered from bodily disease induced by such
study. The sole cause of this was, that they medi-
tated more, lying or walking, and in the open air ; be-
cause they never drank coffee, or used tobacco ; and
because at the same time that they exercised the mind,
they never neglected the care and the exercise of the
body.

CHAPTER IV.

Diseases. Injudicious manner of treating them. Sudden kinds of
death. Propensity to self-murder.

DREADFULLY, has this host of the secret and open
enemies of life increased in modern times. When one
reflects how little a savage of the South Sea Islands
knows of diseases, and then takes a view of an Euro-
pean compendium of pathology, where they are mar-
shalled by regiments and companies, and where their
number amounts to several thousands, one cannot help
being alarmed to find that so much is possible for lux-
ury, corruption of morals, unnatural modes of living,
and excesses. Many, nay, the greater part of these
diseases, are occasioned by our own fault ; and it is
equally certain that new ones may be created by the
like conduct. Others came into the world no one
knows when or how, and were altogether strangers to
the ancients. These are the most inveterate and de-
structive ; the smallpox, the measles, and scarlet fever :
and these even are so far owing to ourselves, that we
suffer them to spread and exercise their ravages, with-
out forming any regulations to check them ; though it is
proved that, by a proper exercise of reason, with the
help of those observations that have been collected, we
might banish them from our boundaries, in the same
manner as they were introduced.
12

178 MEANS WHICH SHORTEN LIFE.

The greater part of diseases act either as violent
kinds of death ; the means of suddenly stopping vital
operation, like the apoplexy ; or as the means of short-
ening it gradually, by being either totally incurable, or,
even when they are cured, by leaving behind them such
a loss of the vital power, or such weakness and derange-
ment of the nobler organs, that a body so affected can
no longer attain to that term of life to which it was
originally destined.

The following short view, collected from different
bills of mortality, will show, in the clearest manner,
how monstrous that los is which mankind sustain at
present by disease. Of a thousand persons who are
born, 24 die at their very birth ; teething carries off
50 ; convulsions and other diseases during the two first
years, 277; the smallpox, which, as is well known,
destroys one in ten, carries off 80 or 90 ; and the mea-
sles 10. If they are females, 8 die in childbed. The
asthma, consumption, and disorders of the chest, at least
in England, destroy 190 ; violent fevers, 150 ; apo-
plexy, 12, and the dropsy, 41. Of a thousand persons
also, we can allow only 78 who die of old age, or rather
at an advanced period of life ; for the greater part of
these will fall a sacrifice to accidental affections. In
short, it hence appears, that nine-tenths of mankind
die always prematurely, and by the effects of disease.

I must here mention also a new and detestable dis-
order, which tends to the immediate destruction of life,
I mean a propensity to self-murder. This unnatural
passion, which prevailed formerly through direful ne-
cessity and heroic resolution, has now become a disease,
which, in the bloom of youth, amidst the most favorable

MANAGEMENT OF DISEASES. 179

circumstances, merely by disgust and satiety of life, can
excite the most horrid and irresistible desire to deprive
one's self of existence.* There are, indeed, men in
whom every source of vital sensation and vital enjoy-
ment is so exhausted, in whom every germ of activity
and happiness is so deadened, that they find nothing so
insipid, so disagreeable, and so disgustful as life ; that
they have no longer any points of contact with the
world which surrounds them ; and that life, at last,
becomes to them such an oppressive burden, that they
cannot withstand the desire of getting rid of it. And
these men, for the most part, are such as, by youthful
dissipation, and too early a wasting of the powers and
vigor which ought to be the seasoning of life, have
exhausted themselves, and become incapable of relish-
ing its enjoyments. Is it not natural that such unfor-
tunate beings should prefer death without all sensation,
to a living death which their life may undoubtedly be
called ?

But the mischiefs of these already too numerous and
dangerous enemies are infinitely increased, because
people in part treat them very improperly, and in gen-
eral abuse medicine too much.

Among those improprieties which regard the treat-
ment of diseases, I reckon the following : "When peo-
ple, notwithstanding every proof of their mischief, suffer
the causes of disease to remain in activity : when one,
for example, evidently observes, that drinking wine, the
use of too light clothing, or sitting up late at night,

* In seventy-five years, twice as many people in London fall
a sacrifice to suicide as to the ple'urisy.

180 MEANS WHICH SHORTEN LIFE.

brings on disease, and yet continues these practices ;
also, when one totally mistakes the disease, or will not
allow that any exists, by which means a very trifling
indisposition may be converted into a serious malady.
And here I cannot help particularly mentioning a neg-
ligence to which the lives of thousands are undoubtedly
sacrificed ; I mean neglecting a catarrh or cough.
People in general consider this as a necessary, and, in
part, useful evil ; and in that respect they are right, if
the catarrh be moderate, and do not continue too long.
But one ought never to forget that every catarrh is a
disease, and may readily end in an inflammation of the
lungs, or, what is more frequently the case, in an
asthma or consumption ; and I do not say too much when
I assert, that one-half of all the asthmas arise from ca-
tarrhs which have been thus neglected. Such mischief
follows when they continue too long, or have been im-
properly treated ; and I therefore recommend the two
following rules, which ought to be sacredly observed by
every one who is attacked by a catarrh of the chest.
One must not overlook a catarrh cough more than a
fortnight ; if it continue longer, it must be considered as
a disease, and be treated by a physician. Secondly,
during the time every catarrh lasts, one must guard
against violent heating of the body, cold, and the use of
spices, wine, and other spirituous liquors.

It is also a too common mode of improperly treating
diseases, that people often, partly from ignorance or
prejudice, and partly through mistaken tenderness, do
exactly the contrary of what ought properly to be done.
Of this kind are, when people oblige the patient to eat,

FREQUENCY OF VIOLENT DEATH. 181

though he has no appetite ; when, during feverish dis-
orders he is suffered to use beer, wine, coffee, meat-
soups, and other rich and nourishing things, by which
the slightest degree of fever may be changed into the
most violent ; when people, on the patient's complaining
of a fever, and that cold which is connected with it,
bury him immediately under bed-clothes, shut up the
doors and the windows, and heat the air of the apart-
ment as much as possible ; and when they do not pay
sufficient attention to cleanliness and ventilation. This
injudicious treatment destroys more of mankind than
disease itself; and is principally the cause why, in the
country, so many strong sound men fall a sacrifice to
death ; why diseases there so readily assume a malig-
nant quality ; why, for example, the smallpox is more
destructive there in winter than in summer, because
people shut the doors and windows, and, by artificial
means, keep up in the patient's bed-chamber a heat
equally great perhaps as that which prevails during the
summer.

And lastly, I reckon among these improprieties, when
one consults no physician, or consults one that is unskil-
ful, uses medicine injudiciously, has recourse to quacks,
and employs secret means, universal remedies, etc., of
which I shall treat more at length when I come to the
rational use of medicine.

The violent kinds of death also sweep off an immense
number of mankind ; and these, in modern times, have
unfortunately made great progress. Not only have a
more enlarged spirit of enterprise, the greater frequency
of sea-voyages, and more extensive trade, multiplied
such accidents ; but people have fallen upon inventions

182 MEANS WHICH SHORTEN LIFE.

for accomplishing the object of shortening life in an
incredibly quick and refined manner. I shall here
mention only gunpowder, and several new sorts of poison,
such as Aqua Toffana, Succession Powder, etc. Nay,
the art of killing has now become a peculiar and ex-
alted science.

CHAPTER V.

Impure air. Men living together in large cities.

ONE of the greatest means of shortening human life
is, men living together in great cities. Dreadful is the
preponderance which the ravage thence occasioned has
in the bills of mortality. In Vienna, Berlin, Paris,
and London, the twentieth or twenty-third person dies
annually ; while in the country around them, the pro-
portion is only one in thirty or forty. Rousseau is per-
fectly right when he says that men, of all animals, are
the least formed for living together in great multitudes.
The breath of a man is deadly for his fellow-creature ;
and this is the case both in a proper as well as a figu-
rative sense. The moisture, or, as it is commonly
called, the thickness of the air, is not what alone makes
it prejudicial, but the animalization which it acquires
by so many people being crowded together. We can
at most breathe the same air only four times ; for it is
then, from the finest support of life, converted by our-
selves into the most deadly poison. Let one now only
reflect on the atmosphere of such monstrous places,
where it is impossible for an inhabitant to inspire a
mouthful of air that has not been for some time already
in the lungs of another. This produces a general secret
poisoning, which, upon the whole, must necessarily
shorten the duration of life. Those men who are able,

184 MEANS WHICH SHORTEN LIFE.

ought to avoid living in great cities : they are open
sepulchres for mankind ; and not only in a physical, but
in a moral point of view. Even in cities of moderate
size, where perhaps the streets are somewhat narrow,
people should prefer a residence in the suburbs ; and it
is at least their duty to quit the city atmosphere for an
hour or half an hour every day, merely in order that
they may inspire a little fresh air.

CHAPTER VI.

Intemperance in eating and drinking. Refined Cookery. Spirituous
liquors.

THE first thing which, in regard to diet, can act
as a shortener of life, is immoderation. Eating and
drinking too much is prejudicial to life two ways. It
overstrains the powers of digestion, and thereby
weakens them. It prevents digestion, because with
such a quantity the whole cannot be properly prepared;
arid crudities*in the intestines, and bad juices are tle
consequence. It increases also proportionably the
quantity of the blood, and thereby accelerates circula-
tion and life ; and besides, it gives rise to indigestion,
and the necessity of using evucuants, which always
weaken.

To eat too much, means when people eat till they
can eat no longer; and the following are the signs:
When one experiences a heaviness and fulness of the
stomach, yawning, eructation, drowsiness, and confusion
in the head. The old rule, which contains much truth,
ought therefore to be always observed : Give over eat-
ing while you have still some appetite left.

Too refined cookery belongs to the same class. Un-
fortunately I must here exclaim against this friend of
our palate, as one of the greatest enemies of life; as
one of the most destructive inventions for shortening it,
and in the following mariner:

186 MEANS WHICH SHORTEN LIFE.

1st. It is well known that the principal part of this
art consists in making every thing piquant and stimula-
ting. Every article of food, therefore, is half com-
posed, according to this preparation, of hot, stimulating
substances; and instead of accomplishing, by eating,
what is the natural object of it, nourishment and resto-
ration, we increase rather, by irritation, internal con-
sumption, and actually produce the contrary. After a
meal of this kind one has always an artificial fever; and
those who use such food may justly say, consumendo
consumimur.*

2nd. The worst is, that people, by this cookery, are
always induced to eat too much. They become such
friends to their palate, that every remonstrance of the
stomach is ineffectual; and as the palate is always
tickled in a new and agreeable manner, the stomach
has thrice or four times as much labor as it is capable
of performing. For it is a very common fault, that one
does not make a distinction between the appetite of the
palate and that of the stomach ; but considers that as a
real, which is only a false, appetite ; and this error is
by nothing favored so much as refined cookery. Man
thereby loses, at length, one of the greatest supports
of life, the property of knowing when he has had
enough.

3rd. One grand maxim in this cookery is, by the
most unnatural and most variegated compositions, to
produce new stimulants, and new dishes. And hence
it happens that things which singly and alone were per-
fectly harmless and innocent, acquire, by combination,
properties altogether new and destructive. Acids and

* In consuming we are ourselves consumed. EDITOR.

INTEMPERANCE IN EATING. 187

sweet substances, for example, do not hurt when used
separately ; but when used together, they may become
prejudicial. Eggs, milk, butter, and flour, are each,
used by itself, very easy of digestion ; but when joined
together, and formed into a fat solid pudding, the produce
will be extremely heavy and indigestible. It may,
therefore, be laid down as a fundamental principle, that
the more compounded any kind of food is, the more
difficult it will be of digestion ; and what is still worse,
the more corrupt will be the juices which are prepared
from it.

4th. A grand acquisition in the newest mode of
cookery is the art of bringing nourishing juices into
the body in the most concentrated form. Hence we
have consommes jus, coulus, and many other things of
the like kind. By expression and boiling, people have
found means to concentrate the substance of several
pounds of beef, capon, and marrow-bones, into the small
size of a jelly or soup; and they imagine they have
accomplished something great when they send such an
essence of nourishment immediately, and at once, into
the blood, without exposing the teeth to the trouble of
chewing, or the stomach to the labor of digesting. That
is to say, people imagine they can restore themselves
full gallop ; and this is the favorite system of those who
consume themselves in that manner. But these people
are miserably deceived ; for,

In the first place, one can never deviate from the
regulations of Nature without injury. Not without
reason has it been made a law, that the stomach can
receive only a certain quantity ; a degree more would
be too much for the whole. Everybody can admit only

188 MEANS WHICH SHORTEN LIFE.

a proportionable quantity of nourishment; and this
capacity of the whole is always in direct ratio with the
stomach. Man here defrauds Nature : he goes beyond
the first principle, if! may say so; and smuggles, as it
were, into the body, thrice or four times as much nour-
ishment as it is capable of receiving. The consequence
is, a continual plethora of all the vessels ; and this
always destroys the equilibrium as well as the health,
and, in the end, life itself.

Secondly, it has been established by Nature, on
grounds equally good, that our nourishment should be
used in a form rather coarse. The advantage of this
law is, that our food is first chewed in the mouth,
macerated, and mixed with saliva: in the next place,
that it is longer retained in the. stomach, in order, by its
stimulating quality, to incite the stomach to more reac-
tion : consequently it is much better assimilated and
changed into the nature of our substance. On this
properly depends real restoration; for nourishment can
pass into our bodies, and become truly useful to us, only
after it has been, by the powers of the stomach, ren-
dered homogeneous and similar to our substance.

By trangressing this first principle, one creates in the
body juices, which, because they have not been suf-
ficiently assimilated, are unable to effect proper restora-
tion; which, as foreign particles, tend rather to irritate;
and thus promote consumption, much more than resto-
ration.

In my opinion, therefore, it is highly proper that an
art which prevents restoration, which fills us with raw
undigested juices, and which increases internal con-
sumption, should be considered, not as a friend of our

SPIRITUOUS LIQUORS. 189

life, but as one of its most essential enemies. One might
almost imagine that it was invented to convert one of
the noblest gifts of God into a secret poison.

Lastly, we may place in this class, of things that tend
in a particular manner to shorten life, all preparations
of spirituous liquors, which, under whatever name
known, are, in that respect, highly prejudicial. "When
people drink these, they drink liquid fire. They accele-
rate vital consumption in a dreadful manner ; and make
life, in the properest sense, a process of burning.

CHAPTER VII.

Passions and dispositions of mind which shorten life. Peevishness.
Too much occupation and business.

CERTAIN habits and dispositions of mind, such as
melancholy, care, dejection, fear, anxiety, faint-hearted-
ness, and, in particular, avarice and hatred, which are
hostile to life, claim a distinguished rank among those
means which tend to shorten it.

All these exhaust the finest of the vital powers ; de-
stroy, in particular, digestion and assimilation ; weaken
the vigor of the heart ; and, by these means, impede
the important business of restoration. The first or mel-
ancholy affections act, however, negatively in shorten-
ing life. On the other hand, those of avarice and hatred
have, as it were, a positive property of bringing on
death. They not only deprive the body of its vital
powers, but, as they incessantly sharpen the bile, they
are continually preparing a secret poison ; and by the
general irritation of the bile, increase, in an extraordi-
nary degree, self-consumption. That motto, therefore,
is highly proper : Avarice consumes itself.

To these belongs that malignant disposition of mind
known by the name of peevishness. Nothing can so
much blast the bloom of life, shut up every access to
pleasure and enjoyment, and change the beautiful stream
of life into a stagnated puddle, as this disagreeable habit.

PEEVISHNESS. FEAK. 191

I advise every one who regards his life to fly from this
deadly poison, and never to suffer it even to approach.

Fear, also, deserves here a particular place. It be-
longs, in like manner, to those bad habits of mind which
one can harbor or banish at pleasure.

Walter, an Englishman, who sailed round the world
with Anson, was conversing one day with young Berk-
enhout ; and as the latter happened to mention the
word Fear, Walter, with some emotion, replied, Fear is
a base passion, beneath the dignity of man. And, with-
out doubt, it is one of the most absurd : a passion which
debases and degrades man, as much as its opposite
passion, courage, can exalt and elevate him above
human nature. Fear robs him of power, reflection,
judgment, resolution ; in a word, of all that preemi-
nence which the human mind enjoys ; and, to accustom
children not to fear, ought to be one of the first prin-
ciples of education. But, unfortunately, the direct con-
trary is the case. I shall here enlarge on two only of
the most usual kinds of fear : fear of thunder, and fear
of apparitions or spirits. Now he who is subject to
both these may bid farewell to happiness and tranquil-
lity. The period of night, which by its obscurity is so
wisely destined for sweet repose, is to him the signal
of the most painful uneasiness. While others enjoy
peaceful sleep, he listens with trembling and dismay to
the smallest sound ; the sweat of horror bursts forth
from every pore of his body ; and he is more fatigued
in the morning, than at the moment when he lay down.

The joyful season of summer is to him also a period
of terror and dread ; and every fine day brings with it
the idea of thunder, and the apprehension of danger.

One may easily comprehend what destructive influ-

192 MEANS WHICH SHORTEN LIFE.

ence such continual misery must have on the duration
of life. Fear is an incessant cramp ; it contracts all
the smaller vessels ; the whole skin grows cold, and
perspiration is completely checked. The blood is col-
lected in the interior large vessels ; pulsation becomes
irregular ; the heart is overcharged, and cannot move
with freedom. The important business of circulation is
therefore deranged. Digestion is also interrupted, and
crampish affections take place. All the muscular power
is palsied ; the sufferer attempts to run, but is not able ;
he is seized with a general shivering ; he breathes short,
and with difficulty ; in a word, fear has all those effects
which are produced by a mortal secret poison, and its
consequences are equally pernicious in shortening life.

It is impossible for me to omit here a characteristic
of modern times, which certainly deprives us of a valu-
able part of our life : namely, that unfortunate spirit of
restless enterprise (polypraymosine), which at present
subdues a great part of the human race ; an incessant
fickleness, and propensity to new undertakings, new
labors, and new plans. The genius of our age seems
to incline men, much more than is natural for them, to
reflection, activity, speculations, and reformation of
every kind ; and to exercise with more vigor all the
powers which they possess : for the great increase of
luxury, by still multiplying its wants, makes new schemes
and new exertions of the faculties always more neces-
sary. Hence arises that endless uneasiness which de-
stroys all sensation of internal tranquillity and con-
tentment ; which never suffers men to enjoy that degree
of peace and relaxation indispensably requisite for re-
storing them ; and which, consequently, in an alarming
manner, accelerates consumption.

CHAPTEE VIII.

The fear of death.

No kind of fear is attended with more unhappiness"
than the fear of death. He who is subject to it dreads
something which is totally unavoidable, and against
which we can never be a moment secure. He enjoys
pleasure with trembling and anxiety ; he denies himself
every thing, because every thing may be the vehicle of
death ; and by this everlasting apprehension of losing
life, he loses it in reality. No one who feared death
ever attained to a great age.

Love life, and fear not death ! is a command and a
prophecy, the only true frame of mind to become happy
and old ; for, whoever fears death may bid farewell to 1
happiness. To him no enjoyment is pure ; every plea-
sure is poisoned with the idea of death ; he is always
like a malefactor pursued ; the enemy is continually at
his heels ; and yet there are an immense number of
people who are not able to banish from them this
disease of the mind. For the benefit of these I shall
here lay down some rules, which, though they may not
display much metaphysical acuteness, I can recom-
mend as good preservatives against the fear of death ;
and which I know by experience, to have been effec-
tual :

1st. Let a man make himself very familiar with the
13

194 MEANS WHICH SHORTEN LIFE.

idea of death. He alone, in my opinion, is happy, who
has so often, and in so undaunted a manner, looked this
unavoidable enemy in the face, that by long custom, it
has at length become to him a matter of indifference.
How much do those deceive themselves who imagine
they have found, in banishing the thoughts of death,
the best remedy for the fear of it. Before they are
aware, amidst the most lively enjoyment will the idea
rush upon them, and derange them the more, the less
they are acquainted with it. In a word, I can call
those alone fortunate who have carried this custom so
far, that in the moment of joy they can think of death
-without being depressed ; and my readers may believe
me, for 1 assert it on my own experience, that, by often
dwelling upon this idea, and moderating its appearances,
we shall at length acquire a wonderful indifference re-
specting it. Let us only turn our attention to soldiers,
sailors, and miners. Where shall we find men more
contented and happy, more susceptible of every joy ?
And for what reason ? Because, by their continual
approach to death, they have learned to despise it. He
who no longer fears death is alone free ; there is no-
thing else that can fetter his senses, disturb him, or
render him unhappy. His soul is filled with exalted
and undaunted courage, which strengthens the vital
power, and which is therefore a positive means of re-
moving this fear.

This custom is attended also with some concomitant
'circumstances which are undoubtedly of no little im-
portance. It is an excellent help to enable one to
^continue honest and virtuous. On every occasion of
-doubt, when the question arises whether an action be

FEAR OP DEATH. 195

right or wrong, let a man think only on the last hour
of his life, and ask himself, Wouldst thou then do so ;
wilt thou then wish to have acted so ? Innocence is
certainly that happy state, that enjoyment of life, which
can enable a man to think on death without terror. If
a man harbor enmity or revenge against another, if he
entertain a wish of avenging an injury done to him, let
him only reflect on that hour, and on the state in which
hfs thoughts will then be, and I engage that his ideas
of enmity and revenge will immediately forsake him.
The reason is, that, by thus changing the theatre of ac-
tion, all those little selfish objects by which we are usu-
ally gaided are removed ; every thing at once appears
in its proper point of view, under its just proportion ;
the deception vanishes, and nothing remains but what
is real.*

* Allied with the fear of death is the foolish objection which
some people have to making their wills, and doing that which
none others can do so well as themselves, namely, arranging
their affairs. Indeed I have known some so irrational as to en-
tertain alarm at the insurance of their lives ; as though the
thought on death could hasten its approach. The duty of mak-
ing a will is one which ought to be performed by every person,
the moment he arrives at man's or woman's estate, and the neg-
lect of that duty I regard as a dangerous sin. The great Locke,
in a letter to Lord King, has these memorable reflections on
making his will : "I shall not die the sooner for having cast
up my reckoning, and, judging as impartially of my state as I
can, I hope I shall not live one jot the less cheerfully the time
that I am here, nor neglect any of the offices of life whilst I
have it ; for whether it be a month, or a year, or seven years
longer the longest any one out of kindness or compliment can
propose to me is so near nothing when considered and in re-
spect of eternity, that if the sight of death can put an end to

196 MEANS WHICH SHORTEN LIFE.

2d. Many fear death much less than the operation
of dying. People here form the most singular concep-
tion of the last struggle, the separation of the soul from
the body ?> and the like. But this is all void of founda-
tion. No man certainly ever felt what death is ; and
as insensibly as we enter into life, equally insensibly
do we leave it. The beginning and the end are here
united. My proofs are as follows : First, man can
have no sensation of dying ; for to die, means nothiiTg
more that to lose the vital power ; and it is the vital
power by which the soul communicates sensation to the
body. In proportion as the vital power decreases, we
lose the power of sensation, and of consciousness*; and
we cannot lose life, without at the same time, or rather
before, losing our vital sensation, which requires the
assistance of the tenderest organs. We are taught also
by experience, that all those who ever passed through
the first stage of death, and were again brought to
life, unanimously asserted that they felt nothing of dy-
ing, but sunk at once into a state of insensibility. Let
us not be led into a mistake by the convulsive throbs,
the rattling in the throat, and the apparent pangs of
death, which are observed in many persons when in a
dying state. These symptoms are painful only to the
spectators, and not to the dying, who are not sensible of
them. The case here is the same as if one, from the
dreadful contortions of a person in an epileptic fit,
should form a conclusion respecting his internal feelings.
From what affects us so much, he suffers nothing.

the comforts of life, it is always near enough, especially to one
of my age, to have no satisfaction in living." Lord King's Life
of Locke, 2d edit. p. 40. EDITOR.

FEAR OF DEATH. 197

3d. Let one always consider life, as it really is, a
mean state, which is not an object itself, but a medium
for obtaining an object, as the multifarious imperfec-
tions of it sufficiently prove ; as a period of expansion
and preparation, a fragment of our existence, through
which we are to be fitted for and transmitted to other
periods. Can the idea, then, of really making this
transition ; of ascending to another from this mean
state, this doubtful problematical existence, which never
affords complete satisfaction, ever excite terror ? With
courage and confidence we may, therefore, resign our-
selves to the will of that Supreme Being, who, without
our consent, placed us upon this sublunary theatre ; and
give up to his management the future direction of our
fate.

4th. Remembrance of the past, of that circle of
friends who were nearest and always will be dearest to
our hearts, and who, as it were, now smile to us with a
friendly look of invitation from that country of dark-
ness, will tend also very much to allay the fear of death.

CHAPTER IX.

Idleness. Inactivity. Languor.

BUT an opposite conduct, that of neglecting to exer-
cise our powers, may tend also to shorten life; because,
by these means, the organs will soon become unfit for
use ; and derangement of them, interrupted purification
of the juices, and bad restoration must be the conse-
quence. It was the first and unalterable destination of
man, that he should earn his bread by the sweat of his
brow. And this principle is fully confirmed, in a physi-
cal sense, by experience : he who eats without labor
will never thrive. If the necessary proportion be not
preserved between restoration and self-consumption, it
is impossible to retain health or prolong life. If we
consult observation, we shall find that no idler ever at-
tained to a great age, and that those who have been dis-
tinguished by their longevity were all men whose lives
had been extremely active and laborious.

But mental idleness is hurtful, as well as bodily; and
I now come to a means of shortening life, which per-
haps my readers did not expect, because it apparently
makes the time appear to us so long : I here allude to
languor. Let us examine the physical effects of it a
little closer, and we shall see that this unpleasant state
of mind is by no means a matter of indifference, but
that it is attended with very important consequences to

IDLENESS. INACTIVITY. LANGUOR. 199

the condition of our bodies. What do we remark in a
man who is subject to languor ? He begins to yawn ;
this already betrays that the passage of the blood
through the lungs is interrupted. The power of the
heart and vessels suffers of course, and becomes too tor-
pid. If the evil continue longer, accumulations and
stoppages of the blood take place. The organs of di-
gestion acquire a tendency to weakness ; and inactivity
and debility, melancholy, flatulency, and hypochondriac
affections ensue : in a word, all the functions are thereby
weakened and deranged ; and I think I may with truth
affirm, that a state which disturbs the most important
operations of the body, and which enfeebles the noblest
powers, is a shortener of life also.

Languor, in a physical as well as a moral view, is a
state of danger. Weikard mentions the instance of a
child born of poor parents, who were obliged to earn
their bread by their daily labor. The state of this
child, from its birth, was therefore languor. At first
the parents suffered it to lie alone in its cradle, where
it spent its time in looking at its hands and feet. When
it became bigger, it was always shut up in a hen-house,
where it could see only through a small hole. What
was the consequence? The child, when it grew up,
remained heavy and stupid ; showed no signs of reason,
and could scarcely speak.

Nay, it is attended with effects still more destructive.
With a melancholy temperament, languor may at length
conduct one to self-rnurder. A dull English author,
who has written a voluminous work on suicide, relates,
that he one day met one of his countrymen who exhibit-
ed every appearance of deep thought. " Whither art

200 MEANS WHICH SHORTEN LIFE.

thou going, my friend ? " said the author. " To the
Thames, to drown myself." " I beg of yon," replied
the author, " to return home for this time, and to read
over my work on suicide." " God forbid ! " answered
the other. " It was reading that cursed, tedious book,
which excited in me such a dreadful disgust of life that
I am now firmly resolved to drown myself."

But I think I hear every one ask, What in the world
is the best remedy for languor ? It accompanies us to
the ball, to the play-house, to the tea-table, in our walks ;
in short, it is impossible for us to get rid of it! What
you say is perfectly true, but it does not relieve us.
There is only one, but not a very agreeable remedy for
it, and that is regular employment.

CHAPTER X.

Overstrained power of the imagination. Imaginary diseases.
Sensibility.

IMAGINATION was given us as the seasoning of life ;
but as physical seasoning must not be made our daily
nourishment, our mental life, in the like manner, must
not abuse this seasoning of the soul. Too much of it
will, indeed, exalt vital sensation ; but one thereby in-
creases intensive life together with consumption, and
prevents restoration, as is proved by the meagreness of*
such people as have fervid imaginations. Besides one,
by these means, disposes the body to sudden as well as
violent revolutions, which may become dangerous to
life, because, with an overstretched imagination, it is
possible for a small spark to produce a most dreadful
explosion. He, therefore, who wishes to live long,
must never suffer this power of the soul to assume a
superiority, or to occasion a continued state of exalta-
tion ; he will apply it to that purpose for which it was
bestowed upon us, to give a higher lustre to the agree-
able moments of life, to season the unfortunate or insipid,
and to enliven the melancholy.

This faculty may be highly prejudicial to life, when
it acquires certain tendencies, which, by their collateral
effects, produce double mischief; and of these, two ap-

202 MEANS WHICH SHORTEN LIFE.

pear to me to be particularly dangerous, a propensity
to imagine diseases and too great sensibility.

The first disease of the imagination is principally pe-
culiar to hypochondriacs ; but may be excited in those
who are not physicians, if they read works on medicine,
which they do not, like professional men, apply to the
art, but to their own persons ; and who, for want of
sufficient knowledge, conjecture often very erroneously.
Of this I have seen astonishing instances. Not only
people who, with features perfectly regular, supposed
that their noses stood awry ; and who, though slender
and sound in every respect, could not get rid of the idea
that they were in the last stage of the dropsy, but I
have seen a lady who, if asked whether she had not
this or the other local disorder, felt in a mom'ent every
'symptom of it. Having asked her if she had not the
headache, she was instantly seized with it; and on
asking, in the like manner, respecting the cramp in the
arm, and the hiccup, both these affections immediately
took place.

Tulpius mentions the instance of a man who, by read-
ing a great number of medical and chirurgical books,
became quite frantic.

Monro saw a man, who, by studying medicine under
Boerhaave, had become hypochondriacs!. Whenever
he attended any of Boerhaave's lectures, he always
imagined that he was affected with the disease which
had been the subject of it. By these means he was a
continual living commentary on the science of physic ;
but he had scarcely gone half through this destructive
course of medicine, when he found himself so wretched
and exhausted that he was obliged to give up the study
altogether. Nay, we have had the instance of a per-

EXTREME SENSIBILITY. 203

son who imagined himself to be actually dead, and
who, therefore, would have been starved, had not a
friend, who pretended to be dead also, persuaded him
that it was customary in the other world to eat a suffi-
cient quantity daily.

The misfortune attending this weakness not only is
that it occasions constant fear and dread, and that many
diseases are actually excited because people suppose
they are afflicted with them, but it induces patients to
have recourse to useless and preposterous medicines,
and to quackery without end, which often consume the
body much more rapidly than the disease itself would,
did it really exist.

No less dangerous is the second disease of the imagi-
nation, sensibility ; a romantic turn of mind, melan-
choly enthusaism. It is altogether the same whether
one really suffers under distressful events, or, by read-
ing romances and indulging sensibility too much, has
made oneself so feelingly alive to every impression
as to be overcome by the sensation it occasions.
Nay, the latter case is the more prejudicial ; as the one
is the natural state, but the other artificial ; and its
affections are, therefore, more violent and stronger!
We have already seen how highly destructive melan-
choly is to the vital power and to every vital movement.
One may easily comprehend, then, how baneful such a
state must be, which subjects the mind to continual
affliction at the hazard of life, and which cannot par-
take in refined pleasures without tears and heart-break-
ing sensations. What extinction of all energy, of all
cheerfulness and courage ! Two years spent in such a
state of ahguish, would undoubtedly shorten life in a
considerable degree.

CHAPTER XI.

Poisons physical as well as infectious.

BY these I understand all those substances which,
even in small quantity, are capable of producing very
prejudicial or destructive effects on the human body.
Of these there is a great abundance in nature, and of
various kinds. Some act violently, others secretly ;
some suddenly, others slowly ; some externally, others
internally ; some visibly, others invisibly ; and it can-
not be denied that they may be classed among the most
general and the most dangerous enemies of life.

I consider it, therefore, very necessary, as an essen-
tial part of that universal knowledge which ought to be
cultivated among mankind, that every one should learn
to know and to guard against these poisons ; because
people otherwise may, through mere ignorance and
inattention, be liable to be poisoned a thousand ways.
Animals have instinct to enable them to distinguish and
to avoid poisons ; man has reason and experience ; but
these, in this respect, are far from being sufficiently
employed. My object, therefore, here, is to give man-
kind such a comprehensive knowledge and conception
of their danger as may induce them to guard against
these enemies of life.

It is a very hurtful prejudice that people, in common,

POISONOUS METALLIC SALTS. 205

consider nothing as poisonous but what can be received
through the mouth. On the contrary, we may be poi-
soned externally, as well as internally, through every
part of our bodies, so far as they have absorbing ves-
sels ; through the mouth and stomach, through the
whole superficies of the skin, the nostrils, the ears, and
the lungs, by means of bad air. The only difference is,
that the effects, in many parts, take place slowly ; in
others, rapidly ; and that many kinds of poison have an
effect, in particular, upon one part, and some upon
another.

I divLle poisons in general into two classes, physical
and contagious ; the latter of which are distinguished
by their being generated in a living body, and possess-
ing the power of communicating themselves to another.

Among physical poisons, a knowledge of the follow-
ing is particularly necessary :

Arsenic, better known under the name of rat-poison,
is the most violent of all. The smallest dose (five or
six grains) is sufficient to destroy a person with the most
excruciating torture. Numberless are the instances of
people having suffered a severe death from it, but
rather through ignorance and carelessness than through
intention. I am of opinion, therefore, that it would be
much better if this horrid poison were entirely banished ;
especially as it is of so little use, and is employed
almost for nothing else than to kill rats and mice. At
any rate, it ought not to be kept by grocers and apothe-
caries, near drawers where there is coffee, sugar, or any
article used as food. In the mean time, I consider it
as my duty to call the public attention to a few ways in
which poisoning by arsenic may very easily be possible ;

206 MEANS WHICH SHORTEN LIFE.

in which it often happens ; and to warn mankind
against them. One of the most frequent is, when it
is used to destroy vermin. If one reflects how many
people have been deprived of existence by poison des-
tined for mice, this practice ought to be altogether
abandoned. Let not any one imagine that all danger
may be prevented by great caution. I know an in-
stance where some sweet milk, standing in a cellar,
was poisoned by mice who had used some of it after
eating rat-poison. It is much safer to employ for the
same purpose poison-nuts, (Nux vomica) ; which are
far less hurtful to man, but at the same time are a
strong poison for animals. Another kind of poisoning
with arsenic, less observed, is that by means of arsen-
ical colors. Painters by profession know how to secure
themselves against it ; but amateurs and children should
be very cautious in using such colors, and at any rate
.avoid that bad practice of drawing the brush through
their mouth. Equally dangerous are toys painted with
these colors, which ought never to be allowed. Lastly,
I advise every one to guard against a method of poison-
ing with arsenic which is practised by quacks and
mountebanks. These impostors sell abundance of
drops, as a cure for the cold fever, which contain
nothing but arsenic. They indeed often cure the
disease immediately ; but they occasion consumption
afterwards, and other fatal consequences. Let people,
for Heaven's sake, avoid all such arcana.

A poison no less dreadful is lead. It is, perhaps, so
far more terrible, as it acts more secretly as well as
more slowly ; does not discover itself immediately, by
such violent effects ; and because people may be com-

POISONOUS METALS. 207

plctely ruined by it, before it is known that they are
poisoned. With this substance, in particular, poisoning
is possible several ways, which the greater part of the
public have never remarked, and against which I must
here put them on their guard. In the first place, when
people daily swallow with their food and drink some
portion of lead, the most dreadful symptoms, impossible
to be cured, may at length break out, often, even at the
end of some years. This happens when victuals are
dressed in vessels made of tin, which contains much
lead, or in such as are badly glazed ; or when one
drinks wine adulterated with lead. Another very usual
method of poisoning is by painting the face with white
lead, using washes made from lead, etc. All paints are
prejudicial, but chiefly the white, because the whole of
them almost contain white lead ; and the leaden par-
ticles may be conveyed into our bodies, as well through
the skin as through the stomach. Lastly, poisoning
by means of apartments newly painted with Avhite
lead, or oil-varnish, ought not to be forgotten. Who-
ever inhabits these too soon, may, in particular, receive
the poison into their lungs, and become hectic and asth-
matic.

To the same class belong, also, quicksilver, antimony,
and preparations of copper ; which ought all to be con-
sidered as noxious poisons, and which should be guard-
ed against, particularly the last, in regard to cooking
victuals in copper vessels. Even the greater part of
neutral salts, when used in too great quantity at once,
and not sufficiently dissolved in water, may be attended
with poisonous effects. I have met with some instances
where an ounce, or an ounce-and-a-half of alum or salt-

208 MEANS WHICH SHORTEN LIFE.

petre, taken at once, instead of Glauber's salts, excited
every symptom of the most violent poison, and which
could not be removed but with difficulty.

The vegetable kingdom contains a multitude of poi-
sons, which partly occasion death by torpor, such as
opium and deadly nightshade ; and partly by burning
and inflammation, as mezereon and euphorbium. Great
mistakes are committed here, also, through inattention.
Numberless are the instances where people, instead of
chervil (chcenopodium) for salad, have used hemlock ;
instead of parsnips, have eaten the roots of henbane ;
instead of common mushrooms, poisonous fungi ; or used
the berries of the nightshade, mezereon, etc., by which
they brought on death. In every seminary of learn-
ing, therefore, a sufficient knowledge of all the poi-
sonous plants growing in the neighborhood should be
taught.

The poisonous plants most pernicious, and which it
is most necessary to know and guard against, are the
belladonna ; hemlock (cicuta) ; henbane (hyosciamm) ;
wolfsbane (aconitum) ; foxglove (digitalis) ; nightshade
(solanum) ; darnel (lolium temulentum) ; mezereon
(Daphne) ; several sorts of the ranunculus ; poisonous
lettuce (lactuca virosa) ; and the laurel-cherry (lauroce-
rasus). To these belong also bitter almonds, which, ac-
cording to the latest experiments, contain a deadly poi-
son, not inferior to that of the laurel.

The air even, in which we live, can be poisoned so
as to destroy us either suddenly or secretly. I shall
here speak, in the first place, of that poison which we
ourselves communicate to the atmosphere by living and
breathing. Living beings consume, in a certain quan-

POISONOUS PLANTS AND AIR. 209

tity of air, pure substance which we call vital air (oxy-
gen) ; and, in place of it, give back an impure substance
(carbonic acid gas) not fit for breathing. If a great
multitude of people are shut up in a small space, death
may soon be the consequence.* If the space be larger,
and the number less, though death may not ensue, the
effects may be still prejudicial. All places, therefore,
where numerous bodies of people are crowded together,
ought to be avoided ; particularly when they have not
a sufficient height or free passage for the air. This is
most frequently the case in play-houses. One of the
surest signs of the air being poisoned, is when the
lights will no longer burn clear and readily, or here
and there go out of themselves. In an equal degree
is it then unfit for life, because fire and life require the
same part of the air for their support. Those who
keep their sitting apartments or bed-chambers always
closely shut, expose themselves to a slow poisoning of
the like kind. In the same manner may the air be
poisoned when a great many lights are kept burning
in a close room. And the case is the same when one
sleeps in a close bed-chamber where coals are burning,
by which death is often the consequence. When one
keeps in a close bed-chamber, during night, a great
many plants and shrubs, the air experiences a similar
kind of poisoning ; while, on the other hand, the same
plants, in the daytime, and exposed to the sun, render
the air more pure and wholesome. Evaporation from

* This is sufficiently proved by the dreadful instance which
happened in the black hole at Calcutta, where, of 146 English-
men, confined scarcely twelve hours, 123 were destroyed by the
air being thus poisoned.

210 MEANS WHICH SHORTEN LIFE.

putrid substances is capable of producing the like effect.
The strong smelling effluvia of flowers can communi-
cate to the air, in close apartments, a pernicious, and
even , a deadly quality also ; and therefore it is not
proper to keep in one's bed-chamber strong scented
flowers, such as the narcissus, roses, etc.

But far more important and dangerous appear to me
the class of infectious poisons, to which I now proceed ;
and I earnestly request that my readers will pay the
utmost attention to the observations I shall make re-
specting them. Concerning physical poisons, people
may always procure information : there are works
which treat of them ; they are known, and conse-
quently can be avoided. With infectious poisons the
case is quite different. They have been overlooked, as
unavoidable and necessary evils; they have not been
much considered as poisons, but in regard to the dis-
eases which they occasion ; people poison, and are
poisoned; and this dreadful secret trade is carried on
daily and hourly, without men knowing or reflecting
what they are about. Physical poisons, as is proper,
have been subjected to police laws : the State takes care
that they shall be carefully kept, and that the use of
them be limited ; and those who wilfully administer
them to others, are treated as criminals, and punished.
The infectious poisons, on the other hand, are restrained
by no laws, by no police ordinances: they exercise
their ravages among us without interruption ; the hus-
band poisons the wife, the son the father ; and no one
takes any trouble to remedy this evil. Lastly, physical
poisons hurt only the individual ; whereas the infectious
possess the peculiar power of reproducing themselves

INFECTIOUS TOISONS. 211

in every living being, and of multiplying without end ;
they injure, therefore, not only those poisoned, but ren-
der them new sources by which whole neighborhoods
and districts may be infected.

I could here produce the most melancholy instances
of men who merely through ignorance were poisoned
in this manner ; and of some who infected others, even
their nearest friends, because they were unacquainted
with these poisons, and the way in which they are pro-
pagated. I, therefore, consider a knowledge on this sub-
ject so necessary, and so defective among the public,
that I with pleasure embrace the present opportunity
of saying something upon it, which may be of general
utility.

Infectious poisons are such as can be no otherwise
generated than in a living body ; and which possess the
power of reproducing themselves when communicated
to another, and of giving rise to the same corruption
and disease which prevailed in the former. Each class
of animals has one peculiar to itself, and which does not
take any effect upon another. Thus mankind have
some which do not attack animals : for example, the
smallpox. * Animals, on the other hand, are suscepti-
ble of some which do not affect men ; as, the disease
among horned cattle, and the glanders among horses.f
I am acquainted with only one peculiar to men as well
as animals, and that is the poison of canine madness.

* The smallpox is met with in sheep ; and the cowpox is now
recognized as the smallpox of the cow. In my work on " Dis-
eases of the Skin, " I have recorded examples of human small-
pox being communicated to cows. EDITOR.

t Glanders is now too well known to be communicable to man
and to give rise in him to a virulent and fatal disorder. EDITOR.

212 MEANS WHICH SHORTEN LIFE.

A very remarkable difference between these poisons
is, that some of them never appear again without fresh
external infection; as, the smallpox, measles, and
plague : while others may be again produced, without
infection, merely by corruption, and certain changes
which take place in animal bodies ; and among the
latter class are the putrid fevers. It has, therefore,
been often asked, Whence did the poisons of the first
class arise ? And, indeed, it is difficult to answer this
question. The analogy of the latter class, however,
allows us to suppose that they were first generated in
the human body, but through so rare a concurrence of
external as well as internal circumstances that thou-
sands of years, perhaps, must be necessary before the
same thing can again happen. It hence follows, that
these poisons, as they must always, in order to continue,
be produced in a human body, may again cease, as soon
as they have been deprived, either by accident or pre-
cautionary regulations, of an opportunity to regenerate.
A consoling reflection, on which the extirpation, or at
least banishment of them from certain districts depends ;
and of the truth of which we may be convinced by
finding that some of these poisons, such as those of
the pla"gue and leprosy, have, by wise establishments,
been driven from among civilized nations. But this
consequence is also equally well founded, that, by a
new concurrence of uncommon circumstances and cor-
ruption in the bodies of animals, an entirely new poison
of the like kind, hitherto unknown in the world, may
be again created.

Before all these kinds of poison, however, can have
effect, there is necessary, not only a communication or

INFECTIOUS POISONS. 213

infection from without, but also a certain disposition or
sensibility of the body. Hence that remarkable pheno-
menon, that many can be poisoned very easily, some
with difficulty, and many not at all : nay that many of
these poisons can affect us only once, because, by being
once poisoned, the whole sensibility of the body, in
regard to the infection, is destroyed ; as we find to be
the case in the smallpox and measles.

Infection may apparently be communicated in a great
variety of ways ; but it is always confined to this simple
principle, that immediate contact with the poison is
necessary before it can be conveyed to another. This,
however, must be properly understood. One may come
into immediate contact with the poison, either by touch-
ing the body of a diseased person, or any other body
with which the poison is united, or to which it has at-
tached itself; as, for example, clothes, fwrniture, etc.
A few poisons of this kind have the property of diffus-
ing themselves through the atmosphere, as those of the
smallpox, measles, and putrid fevers ; but this con-
taminated air remains poisonous only in the neighbor-
hood of the diseased, or, in other words, the atmos-
phere only around the diseased person is poisonous. If
it be, however, mixed with and thinned by purer air,
like every other poisonous solution, it ceases at length
to have a poisonous effect ; that is to say, the poison
cannot be conveyed by the atmosphere to any great
distance.

My principal view here is to enable that part of the
public unacquainted with physic to guard against these
poisons ; or, what cannot be a matter of indifference to
any person of benevolence, to avoid communicating the

214 MEANS WHICH SHORTEN LIFE.

poison to others when one is infected. I shall, there-
fore, first, give a few rules how people may secure
themselves from infection in general ; and then treat
singly of those kinds of poison which appear most com-
monly among us, and show how they may be dis-
tinguished and avoided.

The best means by which people, in general, may
secure themselves from infection of every kind, consist
in the following rules :

1st. Pay the utmost attention to cleanliness ; for the
greater part of the poisons of this kind are conveyed to
us through the external surface of our bodies : and it is
fully proved, that poison, already communicated, has
been by cleanliness removed before it could actually
produce any bad effect. I here allude, in particular, to
frequent washing, bathing, rinsing the mouth, combing
the hair, andoften changing the linen, clothes, and bed.

2nd. Be careful to admit pure air into your apart-
ments, to enjoy the free air often, and to give the body
proper exercise. By these means, one will preserve
the perspiration and vital power of the skin ; and the
more active these are, the less danger is to be appre-
hended from external infection.

3rd. Let people endeavor to keep themselves in
good spirits, and preserve serenity of mind. Such a
disposition is best calculated to support the counteract-
ing power of the body, free perspiration, and the out-
ward tendency of the juices, by which the catching of
infection is much prevented. This rule is particularly
to be recommended where putrid fevers prevail ; and
there also a glass of good wine may be serviceable.

4th. Avoid coming into close contact with people,

RULES FOR AVOIDING INFECTION. 215

the physical state of whose bodies you do not perfectly
know ; and, in particular, beware of touching them with
parts which have no skin, or one exceedingly delicate
and tender ; such as wounds, the lips ; as, by these, in-
fection is soonest imbibed. Of the like nature is the
touching of substances which a little before may have
been used by others.

5th. When infectious diseases are prevalent in any
district, I would strongly advise people not to go abroad
at night, because one imbibes infection much more
readily in the night than the daytime.

CHAPTER XII.

Old age. Premature ingrafting of it on youth.

Tins is the most unavoidable of all those means that
tend to shorten life. It is a secret thief, as Shakspeare
calls it, the necessary consequence of life itself : for, by
the vital process, our vessels must become gradually
more desiccated and unfit for use, our juices more acrid
and less, the smaller vessels shrivelled, the organs in-
capable of performing their functions ; and the earthy
part, the surest means of our destruction, must gain a
superiority.

It cannot, therefore, be altogether prevented. The
question only will be : Is it in our power to bring it on
sooner or later? And, unfortunately, this question
must be answered in the affirmative. Modern times
afford us astonishing instances of the possibility of
bringing on premature old age, and of causing the pe-
riods of life to follow each other much more rapidly.
We may see at present, particularly in great cities, men
come to maturity in their eighth year ; in their six-
teenth, attain to the highest point possible of their
perfection ; in their twentieth, struggling with every
infirmity, a proof that they are already on the decline ;
and in their thirtieth, have every appearance of ex-
hausted age, such as wrinkles, dryness and stiffness of
the joints, a crooked spine, loss of sight and memory,

PREMATURE OLD AGE. 217

grey hair, and a tremulous voice. I once dissected the
body of such an artificial old man, who had scarcely
attained the age of forty ; and found not only his hair
grey, but the cartilages of the ribs, which do not be-
come bones until the greatest age, totally ossified.

One, therefore, can imitate by art, in our climates,
that hastening of the periods of expansion as well as of
old age, which, in warm countries, takes place naturally.

I must now say a few words on the art of ingrafting
old age on youth. This is done by weakening very
early the vital power as well as the juices, and giving
to the vessels the highest possible degree of hardness,
stiffness, and want of pliability, which characterizes old
age.

I shall here lay before my readers the surest means
to accomplish this, as it is of importance to know sucii
prescriptions, in order that people may be better
enabled to counteract them. If one, therefore, will only
live altogether contrary to the following rules, one may
be enabled to preserve one's self in a state of youth to
an advanced period of life.

1st. Endeavor, by every art physical and moral, to
attain to maturity as speedily as possible, and waste the
vital power with as much profusion as possible.

2nd. Begin very early to expose yourself to the
utmost fatigue. Forced journeys of several days, con-
tinual dancing, sitting up all night, and shortening every
period of rest, will, in this respect, be of most service.
By these means you will accomplish two objects, that
of speedily exhausting the vital power, and that of
making the vessels soon hard and brittle.

3rd. Drink abundance of wine and strong liquors.

218 MEANS WHICH SHORTEN LIFE.

This is an excellent prescription to desiccate the body,
and to make it become shrivelled.

4th. Care, fear, and sorrow, are extraordinarily well
calculated to bring on, very early, every characteristic
of old age. We have instances of persons acquiring
grey hair in the course of one night spent under the
highest degree of grief and terror. Now, one might
believe, that certain causes are absolutely necessary to
produce these affections: but there are people who
understand, in. a masterly manner, the art of seeing
everything in a melancholy light, of dreading some evil
from every man, and pf finding in the most common
circumstances abundant matter to excite wretchedness
and misery.

5th. That system, carried too far, or at least badly
understood, of hardening the organs by the means of
cold, bathing frequently and for a long time in cold
water ; nothing can be more proper to produce every
symptom of age.

But it is not enough that people now attain old age,
in a period during which our ancestors were still young :
they unfortunately go further. They have found out
the art of bringing into the world children with old age
upon them. Such phenomena I have sometimes seen.
These shrivelled beings enter upon the stage of life with
the strongest features of age; and, after two weeks
spent amidst misery and crying, they close their aged
life, or rather begin existence by ending it. But I
shall draw a veil over these horrid productions of
parental dissipation, which appear to me like the em-
bodied sins of the parents.

PART III.
MEANS WHICH PROLONG LIFE.

CHAPTER I.

Good physical descent.

IF we take a retrospective view of the principles on
which longevity depends, and the properties necessary
for promoting it, we shall readily perceive that much in
particular will depend on the mass from which we are
formed ; what quantity of vital power is communicated
to us at our creation ; and whether a foundation be
then laid for a strong or a weak constitution, a sound
or a diseased structure of the vital organs. All this is
intimately connected with the healthful state of our
parents, and the important point of our first existence ;
and in that sense, to be of good birth is what ought to
be wished in regard to every man. It commonly be-
longs to those unknown yet important benefits which
we receive ; and is a means of prolonging life. This
advantage, however, we are not able to procure to our-
selves ; but we have it in our power, and it is our duty
to communicate it to others.

Three points are here to be considered: the state of
health in which the parents are ; the moment of genera-
tion ; and the period of pregnancy.

220 MEANS WHICH PROLONG LIFE.

1st. The state of health, or the vital stock of the pa-
rents. How important this is may be seen by the
instance of whole families in which longevity has been
as it were a privilege ; like the family of the before-
mentioned Parr, who not only attained to a great age
himself, but also his father and children. In the lon-
gevity of parents lies a great ground for enabling their
children to attain to the same. This, therefore, ought
to be a powerful motive to induce those who intend to
have children to spare and preserve their vital power
as much as possible. We are a copy of our parents,
not merely in regard to the common form and texture,
but in respect to particular weaknesses and faults of
single parts. A foundation even for diseases, which
have their root in our structure and constitution, may
be thus communicated. I am convinced, above all,
bv repeated experience, that great weakening of the
constitution by early excesses, communicates to children
a peculiar weakness of the glandular and lymphatic
system, which ends in the scrofula, as it is called ; and
occasions this disease to appear in the first months of
life, or even at the very birth. The too youthful or too
great age of the parents is likewise prejudicial to the
strength and vital duration of the children.

2nd. The moment of generation. This is of much
more importance than commonly believed, and has
great influence, both in a moral and physical view, on
the life of the future being. The first germ of a new
creature is here quickened ; the first vital power is
communicated to it. How much must the perfection or
imperfection of the produce be determined by a perfect
or imperfect, sound or a diseased condition of the active

GOOD PHYSICAL DESCENT. 221

causes ? Is it not to be wished that parents would pay
some attention to this remark, and never forget that the
above moment is of the utmost importance ; that it is
the moment of creation ; and that Nature, not without
reason, has connected with it the highest exaltation of
our existence ? However difficult it may be to collect
observations from experience on this subject, I have
known some undeniable instances where children,
begotten in the moment of intoxication, remained stupid
and idiots during their whole life. Now, what can be
effected by the highest extremity, may be done, on a
small scale, by a mean degree , and why should it not
be admitted, that a being procreated at the period of
ill-humour, bodily indisposition, or nervous debility, may
carry with it, during its whole existence, some- small
particles of these evils ? Hence the evident preference
of the child of love to the children of duty. In my
opinion, therefore, it is of the utmost importance, even
in the married state, that this moment should be con-
fined to a period when the sensation of collected powers,
ardent passion, and a mind cheerful and free from care,
invites to it on both sides ; and this forms a new ground
against the too frequent, forced, or mechanical enjoy-
ment of wedded love.

3rd. The period of pregnancy. Though the father,
without doubt, is the original source from which the
future being acquires its first quickening, its earliest
breath of life, the general mass and most material part
proceeds entirely from the mother. The latter is the
soil from which the seed derives its juices ; and the
future constitution, the proper substance of the child,

222 MEANS WHICH PROLONG LIFE.

must principally assume the character of that being of
whom it makes so long a part, and of whose flesh and
blood it is actually composed. Besides, not only the*
constitution of the mother, but also other favorable or
unfavorable causes, during the time of pregnancy, must
have a great influence on the whole formation and life
of the being. This is confirmed by experience. The
child's state of health, and the greater or less strength
of its constitution are determined, in a particular man-
ner, much more according to the condition of the mother,
than that of the father. By a weakly father a robust
child can always be produced, provided the mother
have a sound and vigorous body. The substance of
the father is, as it were, in her ennobled. On the other
hand, the strongest man will never obtain a lively,
healthy child from a mother who is weak and sickly.
"With regard to the protection of the child during
pregnancy against all dangers and hurtful effects, we
find a regulation which displays the provident care of
Divine Wisdom. Though the most intimate connection
subsists between it and the mother, and though for
nearly a year it forms a part of her, and partakes of
her nourishment and juices, it is secured not only
against accidental injuries by its situation and floating
in a watery element, but also against moral and ner-
vous impressions by there being no nervous connection
between it and the mother. We have, therefore, nu-
merous instances of the mother dying, while the child
continued alive. Nature has even conjoined with this
state a certain immunity from sickness ; and it is a
principle established by experience, that a pregnant

GOOD PHYSICAL DESCENT. 223

woman suffers much less from infectious and otjier
causes of disease ; and that a female has never a greater
probability of living than while in that condition.

So much have mankind been, at all times, impressed
with the importance of this period, that, among ancient
nations, a pregnant woman was considered as a person
sacred and secure from injury, and that every one who
hurt or ill-treated her was thought deserving of double
punishment. Our age, unfortunately, has here made a
difference, both in a physical and a political view. The
weak nerved, sensible, and delicate constitution of the
female sex, at present, renders the preservation of the
fruit in the mother's womb much more uncertain and
dangerous. The womb of the mother is no longer a
place of safety, the undisturbed atelier of Nature.
Through that unnatural sensibility which is now so pe-
culiar to a great part of our women, they have become
far more susceptible of a thousand prejudicial effects, a
multitude of passions ; and the fruit suffers by every
mental affection, every alarm, every cause of disease,
and even by the most trifling accident. It is, therefore,
impossible that a child, in a place where its formation
and expansion are every moment interrupted and dis-
turbed, should acquire that degree of perfection and
strength to which it was destined. And yet little
attention do mankind pay, either in a civil or political
point of view, to the importance of this condition.
Who thinks, at present, on the sacredness of a pregnant
woman ; or, who regulate their behavior to her, by re-
flecting that the life, or at any rate the physical and
moral formation, of a future being may thereby be en-
dangered ? Nay, how few pregnant women take that

224 MEANS WHICH PROLONG LIFE.

care of this condition which it deserves ! and how few
are able to deny themselves that pleasure and those
gratifications which may be attended with mischief!

In my opinion, therefore, the following rules may,
with great propriety, be founded on these observations :

1st. Such highly weak nerved and sensible people
ought never to marry ; if not through a regard for them-
selves, and on account of the sufferings which they may
thereby avoid, at any rate out of compassion for the
miserable race of which they would be authors. In the
education of daughters, people above all things should
be attentive to guard against this unfortunate sensi-
bility ; because, from a regard for the complection, for
appearance, and a multitude of other points which be-
long merely to etiquette, a contrary conduct is observed.
And lastly, it is the duty of every man, when he chooses
a wife, to be particularly careful that her nervous sys-
tem be not too irritable. Should this be the case, the
principal object of marriage, to produce sound and
robust children, is entirely lost.

2nd. Women ought to pay more attention to this
period, and to observe a good moral as well as physical
regimen ; for they have then in their power the degree
of perfection or imperfection, of the good or bad struc-
ture of the mind and body of their child.

3rd. Men in general should have respect for a preg-
nant woman in this point of view ; and, as the deposi-
tary of a human being during its state of formation,
treat her with every care, tenderness, and attention.
Every husband, in particular, ought to make this a
duty ; and to reflect that he thereby watches over the
life and health of his offspring, and deserves, in the
fullest sense, the title of father.

CHAPTER II.

Prudent physical education.

THE physical treatment during the two first years of
existence is, in particular, a very important circum-
stance in regard to the prolongation of life. That
period ought properly to be considered as a continued
generation. The first part only of formation and ex-
pansion takes place in the mother's womb ; the second,
which is no less important, takes place externally dur-
ing the two first years of life. A child comes into the
world as a being only half finished. The most im-
portant and delicate expansion, that of the nerves and
organs of the soul, the organs of respiration, the mus-
cular system, the teeth, the bones, the organs of speech,
and all the other parts, both in regard to form and
structure, now follows. One may readily comprehend,
therefore, what influence the different circumstances,
under which this continued process of formation and
expansion is carried on, whether they act so as to im-
pede, derange, and weaken, or to accelerate, must have
on the perfection and duration of life. A foundation:
may certainly be here laid for slow or rapid consump-
tion ; for a body exposed to more or to fewer dangers.

All the precepts and rules respecting this period may
be reduced to the following principles :

1st. All the organs, but in particular those on which
15

226 MEANS WHICH PROLONG LIFE.

health and the duration of physical as well as spiritual
life chiefly depend, must be completely formed, exer-
cised, and brought to the highest degree of perfection.
Among these I reckon the stomach, the lungs, the skin,
the heart, the vascular system, and the organs of thought.
A foundation may be laid for good lungs, by pure open
air ; and afterwards, by speaking, singing, running ;
for a sound stomach by wholesome food, easy of di-
gestion ; but neither too strong and stimulating, nor
too highly seasoned : for a sound skin, by cleanliness,
washing, bathing, pure air, a temperature, neither too
hot nor too cold, and, afterwards, by exercise : and for
a strong heart and vessels, by all the above means ; in
particular, by wholesome nourishment, and afterwards
by bodily motion.

2nd. The successive expansion of the physical and
spiritual powers must be properly supported; and be
neither impeded, nor too much promoted. Attention
must be always paid to an uniform distribution of the
vital power ; for harmony and equality in the motions
are the foundation of health and life. Bathing and free
air will contribute to this in the beginning, and after-
wards bodily exercise.

3rd. The sensation of the body in regard to disease,
that is to say, its susceptibility of the causes of disease,
must be hardened and blunted ; as also its sensation
of cold and heat, and afterwards that of small irregu-
larities and fatigue. By these means two advantages
will be gained ; vital consumption, by the sensibility
being moderated, will be lessened ; and the derange-
ment of it by diseases will be guarded against.

4th. Every cause and germ of disease in the body

PRUDENT PHYSICAL EDUCATION. 227

must be removed and banished ; such as accumulations
of phlegm, obstructions of the mesentery, and sharp
acrid humors ; faults which may arise from external
hurts and impressions, too confined bandages, want of
strict cleanliness, etc.

5th. The vital power itself must be always sufficiently
nourished and strengthened, particularly by means of
fresh air ; and the healing power of nature must, above
all things, be supported from the beginning, because it
is the principal means which lies in ourselves for render-
ing the causes of disease ineffectual. This may be done
chiefly by not accustoming the body at first too much
to artificial assistance ; otherwise Nature will be so
used that she will depend on foreign aid, and at length
lose altogether the power of assisting herself.

6th. The whole operation of life and vital consumption
must not at first be put into too great activity but be
preserved in a moderate state ; by which means its tone
may be regulated for the whole life, and also for a slow
and a long life.

The following simple means, which, in my opinion,
form the principal part of physical education, may
serve for accomplishing what is contained in the above
precepts.

We must here, however, distinguish two periods.
The first period is from birth to the end of the
second year ; and the chief points to be observed are as
follow :

I. The nourishment must be good, but suited to that
tender age ; easy of digestion, rather fluid than solid ;
fresh and sound ; nutritive, but not too strong, stimulat-
ing, or heating.

228 MEANS WHICH PROLONG LIFE.

Nature, here, is our best guide ; as she has destined
milk to be the earliest food of man. Milk possesses
all the above qualities, in the most perfect degree : it
is full of nutritive substance, but mild and nourishing,
without heating or stimulating : it holds a mean rank
between animal and vegetable food ; unites the advan-
tage of the latter, that of being less stimulating than
flesh, with all the advantages of flesh : that is to say,
its being already assimilated to us by preparation in a
living animal body, which makes it more easily assume
the character of our substance ; and, in a word, it is
altogether suited to the nature of an infant.

The body of a child lives quicker than that of a full-
grown man, and changes oftener its component parts.
Besides, it requires nourishment, not merely for its sup-
port, but for its continual growth, which is never so
rapid during the whole course of life as the first year.
It is evident, therefore, that it has occasion for abun-
dance of concentrated nourishment ; but as its powers of
digestion are weak, it is not able to prepare and assimi-
late food that is solid or heterogeneous to its nature ;
such, for example, as vegetables. Its nourishment must
then be fluid, and already animalized ; that is, be prepared
and rendered like its nature in another animal body.
It has, however, a great degree of irritability and sensi-
bility ; so that a small irritation, which a grown-up
person would scarcely feel, may in it produce an artifi-
cial fever, or the cramp and convulsions. The nourish-
ment of a child must on this account be mild, and ex-
actly suited to its irritability.

I consider it, therefore, as one of the first laws of
Nature, and a principal ground for a long and healthy

PRUDENT PHYSICAL EDUCATION. 229

life, that a child should be nourished, during the whole of
the first year, by the milk of its mother, or of a sound
nurse.

From this law of Nature people in modern times
make many deviations, which undoubtedly have the
most prejudicial influence on the duration of life and
health, and which I must therefore here mention.

Some have attempted to nourish and educate chil-
dren by slimy vegetable substances. These sometimes,
and in particular cases, may be useful, but, without
any other food, are certainly hurtful ; for they do not
afford sufficient nourishment, and, what is worse, do
not become properly animalized, and retain still a part
of their sour vegetable nature in the body of the child.
Such food, therefore, produces weak meagre childien,
continually tormented with acidities at the stomach,
sour eructations, phlegm, obstructions in the glands, and
the scrofula.

Still worse is the custom of nourishing children with
flour-pap ; for this food, besides the disadvantage of its
acid nature, as being a vegetable aliment, obstructs the
tender lacteal vessels, and those of the mesentery ; and
lays a certain foundation for the scrofula and consump-
tion of the lungs.

Others, to avoid these evils, and partly through an-
glomania, make choice of flesh nutriment for their
children, and give them wine, beer, and other things
of the like kind. This prejudice deserves in particular
to be reprobated, because it seems daily to gain more
advocates, because it agrees with the exciting method
so much approved at present, and because the mischief
it occasions is not always sufficiently attended to by

230 MEANS WHICH PROLONG LIFE.

physicians. People say, in common, flesh is strength-
ening; and that is precisely what a child requires.
But the grounds on which I found a contrary opinion
are as follows : There must always be a certain rela-
tion between the nourishment and the body to be nour-
ished, between the irritation and the irritability. The
greater the irritability, the stronger is the effect which
may be produced by a small irritation ; the smaller the
former, the effect of the latter will be so much weaker.
Now, this irritability in human life is always in an in-
verse ratio to the age. In the first period of life it is
strongest ; and it every year becomes weaker, till it is
entirely extinguished by old age. We may therefore
say that milk, in regard to its irritating and strengthen-
ing power, is as exactly proportioned to a child, as flesh
to an adult, or wine to an old man. But if one give
flesh nourishment to a child too soon, one gives it an
irritation like that occasioned by wine to grown-up per-
sons, which is much too strong, and not destined for it
by Nature. The consequences are, that a kind of arti-
ficial fever is produced and kept up in the child, that
the circulation of the blood is accelerated, its warmth
increased, and that a habit with a tendency to violent
inflammatory disorders is created. Such a child has a
full blooming look ; but the slightest cause may occasion
a violent commotion in the blood ; and when it arrives
at the period of teething, or if attacked by the small-
pox, or any other kind of fever, when the tendency of
the blood to the head is so strong, one may rest assured
that some inflammatory disorder, convulsions, or apo-
plexy will ensue. People in general believe that one
can die only through weakness ; but one may die also

PRUDENT PHYSICAL EDUCATION. 231

through too much strength and irritation ; and this may
take place by the injudicious use of irritating things.
Besides, by giving such strong nourishment to children,
one accelerates, from the beginning, their vital opera-
tion and consumption ; the whole system and organs
are put into too great activity ; a foundation is origi-
nally laid for a more vigorous but a quicker life ; and,
under the idea of strengthening, one really establishes
the principal cause of a short life. One also ought not
to forget that, by this early use of flesh nourishment,
the expansive process of teething, and afterwards that
of manhood, are hastened too much, a great means of
shortening life ; and that it has a bad influence on the
whole character. All carnivorous men and animals
are violent, cruel, and passionate ; while, on the o*her
hand, the use of vegetable food inclines men more to
mildness and humanity. This I have often found con-
firmed by experience. Children who had used flesh too
early, and in too great quantity, became always strong
men, but passionate, violent, and brutal ; and I very
much doubt whether such a disposition be fortunate,
either for the individuals, or for mankind in general.
There are certainly cases in which the early use of
flesh nourishment may be useful, particularly for weak
children, educated without the mother's milk, and who
suffer from acidities ; but it is then to be considered
as a medicine, and must be regulated and the quantity
determined by a physician. What I have said respect-
ing flesh is applicable still more to wine, coffee, choco-
late, spiceries, and the like. It is, therefore, a very
important rule, in regard to the physical education of
children, that a child, during the first half-year, should

232 MEANS WHICH PROLONG LIFE.

taste no flesh, no flesh soups, no beer, and no coffee ;
but be nourished merely by the milk of its mother. In
the second half-year, light soups may be admitted ; but
flesh itself ought never to be given till the teeth have
appeared, that is, till the end of the second year.

But as many insuperable circumstances may occur to
prevent a child from being educated in the natural
manner in which it ought ; such, for example, as the
nervous weakness of the mother, or her sickly asthmatic
state, by which the child would lose more than it could
gain in regard to its vital duration ; and if a sound
nurse cannot be procured, the melancholy necessity then
arises of educating the child artificially ; and though this
method is always injurious, in some measure, to the
health as well as duration of life, it may be rendered
less prejudicial by observing the following precepts:
Let the child, at least, where it is possible, derive its
nourishment from its mother for the first fortnight, or
month. One cannot imagine of how much benefit this is
in the first period. As the best substitute for the moth-
er's milk, sheep or ass's milk may then be given ; but
always immediately after it has been milked, and while
it yet retains its natural warmth. It would be still bet-
ter to let the child suck the animal. Should this be
impracticable, let the child have a mixture of cow's milk
and water, always lukewarm ; and fresh milk, at least
once every day. A remark of some importance here
is, that one must not warm the milk, (otherwise it as-
sumes a certain character of acidity,) but only the
water which is added to it. With this artificial nourish-
ment it is necessary to give, somewhat sooner, pap
made of biscuit, pounded very fine, barley, sago, or

PRUDENT PHYSICAL EDUCATION. 233

saloop, boiled with half milk and water ; also light, but
not fat, bouillis and egg-water ; that is, the yolk of an
egg beat up in a pint of water and mixed with a little
sugar. Potatoes during the first two years are preju-
dicial. However little I consider them unhealthful in
general, they are certainly too hard of digestion for so
tender a stomach, as they are of a clammy viscid nature.

II. Let the child, after the third week, (earlier in
summer, but later in winter,) enjoy the free air every
day, and continue this practice without any interruption
on account of the weather.

A perfect similarity prevails here between children
and plants. Give the latter the richest nourishment
and warmth, but deprive them of air and light, they will
become pale, withered, and stunted, and at length die.
The use of pure free air, and of the vital component
parts which it contains, is a nourishment as indispensa-
bly necessary for the support of life as eating and
drinking. I have known people who remained weak
and pale-colored throughout their whole lives, because
they were nurtured during their first years like plants
in a hothouse ; whereas, on the other hand, the daily
use of light and free air is the only means to produce a
blooming complexion, and to communicate strength and
energy sufficient to last one's whole life. This advan-
tage also is of great importance, that a person is there-
by enabled afterwards to bear, without injury, varia-
tions of heat and cold.

It is most beneficial when the child enjoys the free
air in a place covered with grass and trees, at a little
distance from one's habitation. The enjoyment of air
in the streets of a city is far less wholesome.

234 MEANS WHICH PROLONG LIFE.

III. Let the body of the child be washed daily with
fresh cold water: a rule indispensably necessary for
cleansing and invigorating the skin ; for strengthening
the whole nervous system ; and for laying the founda-
tion of a sound and long life.

This practice of washing ought to commence at the
birth ; but during the first week lukewarm water must
be used ; cold water ought to be employed afterwards,
and it is of great importance that it be fresh drawn from
a spring or running stream ; for water contains fixed
air which evaporates when it has stood any time, and
which communicates to it a very strengthening quality.
The child, however, must be washed speedily ; and its
body ought to be immediately rubbed and dried : for
slow bathing cools, but speedy friction warms. Lastly,
it should not be washed when it just comes from bed,
nor, in general, while it perspires.

IV. Every week it ought to be bathed once or twice
in tepid water, warmed to the temperature of new milk,
or from 86 to 91 of Fahrenheit's thermometer.

This excellent practice unites in it such an extraor-
dinary number of virtues, and is at the same time so
suited to the age of infancy, that I may call it a real
arcanum for bringing to perfection and forming the
future man. Cleansing and invigorating the skin, free
but not accelerated expansion of the powers and organs,
uniform circulation, harmonious acting in concert of the
whole (the foundation of health), strengthening the
nervous system, moderating the too great irritability of
the vessels and too rapid vital consumption, purifying
the juices, are all its effects ; and I can, with confidence,
assert that I am acquainted with no assistant means of

PRUDENT PHYSICAL EDUCATION. 235

physical education which possess in so high a degree,
every requisite for laying the foundation of a long and
healthful life. The bath must not consist entirely of
boiled water, but of water fresh drawn from a well, to
which some hot water, sufficient to bring it to a luke-
warm temperature, has been added. In summer that
water is best which has been warmed by the rays of
the sun. The bathing should be continued, at this
period of age, a quarter of an hour each time, and after-
wards longer. It ought never to be used during the
first hour after eating.

V. Be careful not to keep a child too warm : that is,
avoid warm rooms, warm beds, and clothing. Keeping
too warm increases irritability in a great degree, and
gives occasion also to speedier vital consumption ; it
debilitates and relaxes the vessels, accelerates expan-
sion, weakens and deadens the skin, disposes the body
to continual perspiration, and thus renders it always
liable to injury from cold. I consider it of great im-
portance to accustom children to sleep from their in-
fancy on mattresses made of horsehair, chaff, or moss.
These never acquire too much heat ; have more elas-
ticity, and prevent too great tenderness. They oblige
the child also, as they do not yield to pressure, to lie
straight and extended ; by which means they guard
against overgrowth, and the premature excitement of
their organic system.

VI. Let the clothing be wide, in no manner confined ;
and made of some substance not too warm to check per-
spiration, such as fur, but of stuff that can be often
renewed or washed. Cotton is the best ; and during
the severity of winter, light woollen stuffs. Avoid all

236 MEANS WHICH PROLONG LIFE.

.

close bandages, stiff stays, small shoes ; for these may
give occasion to diseases which will afterwards shorten
life. The head, from the fourth to the eighth week,
must be kept quite bare ; but this ought to be deter-
mined by the season of the year.

VII. Pay the utmost attention to cleanliness ; that is,
change the shirt daily ; the clothing every week : the
bed-clothes every month ; and remove every cause of
noxious evaporation ; in particular do not suffer too
many people to be in the nursery ; and allow no clothes
to be dried, or any foul linen to remain in it. Cleanli-
ness for children is one-half of their life : the cleaner
they are kept the more will they prosper and thrive.
By cleanliness alone, with very moderate nourishment,
they may in a short time be rendered strong, vigorous,
and lively ; whereas, without cleanliness, even with the
richest nourishment, they will continue sickly and weak.
Want of attention to this precept is the cause why so
many children pine away and are consumed without
any visible reason. Ignorant people imagine that they
must be bewitched, or under the influence of some evil
spirit ; but dirt alone is the demon by which they are
tormented, and which in the end will undoubtedly
destroy them.

The second period is from the end of the second to
the twelfth or fourteenth year ; and I here recommend
the following precepts ;

I. Let the rules respecting cleanliness, washing with
cold water, bathing, light clothing, and living in free air
be observed according to the foregoing directions.

II. The food must not be too delicate and artificial,
or too coarse. It will be best in this period to allow

PRUDENT PHYSICAL EDUCATION. 237

children a sufficient mixture of flesh and vegetables ;
and to accustom them to every thing, but neither to eat
too much nor too often. People may rest assured that,
if they put in practice all the other rules respecting
physical education, bodily exercise, and cleanliness,
neither delicate nor coarse food will be requisite to
make a child healthy. For the truth of this observa-
tion we need only look at the children of rustics, who,
without being fed according to medical precepts, are
perfectly strong and sound. But one, indeed, ought
not here, as is too often the case, to give a child rustic
fare, and at the same time to indulge it with a soft
feather bed, to confine it to the house, and accustom it
to idleness ; nor to employ the cold bath, while a child,
in other respects, is enervated by most delicate treat-
ment. I cannot repeat too often what I have before
said, that a principal point of education is to preserve
an uniform tone, and not to unite two opposite methods
of management. It will be quite sufficient if a child,
during this period, is allowed four meals every day.
The only things which it ought not to touch are spi-
ceries, coffee, chocolate, seasoning, confections, fat heavy
puddings, and cheese.* For drink nothing is better
than water. In such places only where Nature has
denied pure spring water, I allow children to be accus-
tomed to beer.

III. As bodily exercise now becomes an important

* I cannot conceive ITufeland's reasons for objecting to cheese,
unless, perchance, it were less well made in the eighteenth than in
the nineteenth century. I regard it as a wholesome article of
diet for children, and a good compromise between meat and vege-
table diet. EDITOR.

238 MEANS WHICH PROLONG LIFE.

part of physical education, let a child spend the greater
part of the day in gymnastic sports of every kind, and
in the open air, where they are always most service-
able. This strengthens in an incredible degree ; gives
peculiar activity to the body, uniform diffusion to the
powers and juices ; and guards, in the surest manner,
against faults in the growth and formation.

IV. The powers of the mind must not be exerted too
early. It is a great prejudice, that people imagine
they cannot make a child begin to learn too soon. But
it is certain that a child may begin too soon, when that
period is chosen during which Nature is still employed
in forming the bodily powers and organs, and has need
of all their strength for that purpose. This period
extends to the seventh year ; and if a child be obliged
at an earlier age to apply to learning, and be confined
in a sitting posture, its body will be deprived of the
noblest part of its powers, which must be now wasted
by the business of thinking ; and the consequences will
be, a checking of the growth, imperfect formation of the
limbs, muscular weakness, bad digestion, corrupt juices,
the scrofula, and a preponderance of the nervous system
in the whole machine, which will become burdensome
during life, by nervous affections, the hypochondriasis,
and evils of the like kind. Much, however, will here
depend on the difference of constitution, and the greater
or less vigor of mind ; but I earnestly request that
parents and others will in this respect pursue a method
directly contrary to that usually followed. If a child
show an early disposition for thinking and learning, one
ought, instead of straining its powers the more, as is
commonly the case, to prevent it from application till a

PRUDENT PHYSICAL EDUCATION. 239

later period ; for such premature ripeness is generally
a disease, at any rate an unnatural state, which ought
rather to be checked than promoted, unless one wishes
to breed up a monster of erudition rather than a sound
healthful man.

I must here remark, that a great many of the evils
which attend too early study, may not arise so much
from exerting the powers of the mind, as from confine-
ment and sitting, and from the corrupted air of schools
in which children are taught. At any rate, the weaken-
ing is thus doubled. I am fully persuaded that it would
be much less injurious if children were made to perform
their school business in the open air during the fine
seasons ; and here, at the same time, would they have
before them the book of Nature, which, supposing that
the pupils are capable of reading and understanding it,
is much more fit and proper for their first instruction
than all the books that ever were written or printed.

CHAPTER III.

Active and laborious youth.

IT appears that all those who attained to a great age
were men who, in their youth, had been much ac-
customed to labor and fatigue ; such as soldiers,
sailors, and day laborers. I shall here mention only
Mittelstadt, that veteran of 112, who in his fifteenth
year was a servant, and in his eighteenth a soldier ;
and who was present in all the Prussian wars, from the
commencement of the monarchy.

A youth spent in that manner, becomes the founda-
tion of a long and a strong life, two ways : partly by
giving the body that degree of strength and solidity
which is necessary for its duration ; and partly by mak-
ing that possible which principally contributes to pro-
mote happiness and longevity, advancement to a better
and more agreeable situation. He who in his youth
has every convenience and enjoyment in abundance
hath nothing more to expect ; he is deprived of ttye best
means of exciting and preserving the vital power, hope,
and the prospect of a better condition. If he be con-
demned then with increasing years to poverty and diffi-
culties, he finds himself doubly oppressed ; and the du-
ration of his life must be necessarily shortened. But
in the transition from a state of misery to one more
fortunate, lies a continual source of new joy, new vigor,

ACTIVE AND LABORIOUS YOUTH. 241

and new life. In the like manner, the passage, with
increasing years, from a raw cold climate, to one more
mild, contributes much to prolong life ; as also the
change from a state of labor to one more convenient
and agreeable.

CHAPTER IV.

Abstinence from physical love in youth, and a too early assumption
of the married state.

He who in Pleasure's downy arms
Ne'er lost his health or yonthfal charms,

A hero lives ; and justly can

Exclaim, " In me behold a man! "

He prospers like the slender reed

Whose top waves gently o'er the mead ;

And moves, such blessings virtue follow,
In health and beauty an Apollo.

That power divine, which him inspires,
His breast with noblest passions fires ;

These heavenwards soar with eagle-flight,
And $purn the cold, dark realms of night.

So full of majesty, a god,

Shall earth alone be his abode ?
With dignity he steps, he stands,

And nothing fears ; for he commands.

Like drops drawn from the crystal stream,
His eyes with pearly brilliance beam ;

With blushing signs of health o'erspread,
His cheeks surpass the morning's red.

The fairest of the female train

For him shall bloom, nor bloom in vain :
O happy she whose lips he presses !

happy she whom he caresses ! BUEGEB.

ABSTINENCE FROM PHYSICAL LOVE. 243

THERE was a time when the German youth never
thought of intimacy with the other sex till their twenty-
fourth or twenty-fifth year ; and yet nothing was then
known of the pernicious consequences of this chastity,
nor of many other imaginary evils of which people now
dream : but these youths, increasing in strength as well
as growth, became men who, by their size, excited the
astonishment even of the Romans.

People now leave off at the period when these began.
They imagine they can never soon enough throw off
their chastity ; and young persons, long before their
bodies are completely finished, begin to waste those
powers which are destined for a higher use. The con-
sequences are evident. These men become incomplete,
half-formed beings ; and at the period when our ances-
tors began to employ those powers, they, in them, are
generally exhausted: they feel nothing but dejection
and misery in their weakness; and a stimulus of the
utmost importance for seasoning life is to them for ever
lost.

It is incredible how far prejudice in this respect may
be carried, especially when it flatters our inclination. I
once knew a man who seriously believed that there was
no poison more prejudicial to the human body than
continence, and the consequence was, that he was an
old man in his twentieth year, and in his twenty-fifth
died of old age.

The present age has fallen so much into the taste of
the times of chivalry, that all romances must now as-
sume that form in order to please; and one, indeed,
cannot help admiring the great, noble, and resolute
manner of thinking and acting of these old Germans.

244 MEANS WHICH PROLONG LIFE.

It appears that the more sensible we are how far we
have degenerated from them, the more we are excited
by their example, and the more we are inflamed with a
desire to imitate their conduct. But what a happiness
would it be if we did not think merely of the object,
but of the means to obtain it. That by which these
people acquired so much courage, so great powers both
of body and mind, their bold, firm, and resolute char-
acter, which made them real men in the utmost sense of
the word, was, in particular, their strict continence.
The youth of these men was destined to great exploits
and undertakings, not to voluptuousness and dissipa-
tion ; the physical propensity to love did not among
them sink into mere animal enjoyment, but was exalted
to a moral incitement to noble and heroic actions. Each
bore in his heart the image of his beloved object,
whether real or imaginary ; and this romantic love, this
indissoluble attachment, was the shield of his continence
and virtue, strengthened the powers of his body, and
communicated to his mind courage and unalterable
resolution, by continually directing its attention to his
fair one smiling to him at a distance, and whose favor
could be gained only by glorious achievements. How-
ever romantic these notions may be, I find, on closer
examination, great wisdom in this use of physical love,
one of the strongest motives by which human nature is
actuated. How widely different has the case become
among us ! This propensity, which by prudent man-
agement may be made the germ of the most exalted
virtue, of the greatest heroism, has degenerated into
whining sensibility, or mere sensual gratification, which
people enjoy prematurely, and even to satiety; the

ABSTINENCE FROM PHYSICAL LOVE. 245

passion of love, which in those periods was a security
against dissipation, is at present the source of the great-
est; the virtue of chastity, the principal foundation
without doubt of moral firmness and manliness of char-
acter, has become a subject of ridicule, and is decried
as old-fashioned pedantry ; and what ought to be the
last and sweetest reward of toil, labor, and danger, has
become a flower which every stripling crops by the
way. Why does Nature excite in our bosom this sigh-
ing after union, this all-powerful, irresistible propensity
to love ? Not, truly, to afford subjects for romance, or
to make a figure in the ecstatic raptures of poetry ; but
that it may serve as an indissoluble band to unite two
hearts : to lay the grounds for a ha*ppy generation ;
and that, by this magic tie, our existence may be con-
nected with the first and the most sacred of all duties.
How fortunate would it be were we here to imitate the
ancient method, and never to pull the fruit till we had
planted !

At present, we hear a great deal of strength and
strong men : but I will believe nothing of it as long as
I see that they have not strength enough to subdue
their passions ; for, that is the only cause of triumph,
as well as the only sign of mental strength : and chas-
tity is the school in which youth ought to be exercised,
and to form themselves for becoming strong men.

We in general find, in the old world, that all those
from whom any thing great or glorious was expected,
were obliged to restrain physical love. So much were
people then convinced that Venus absorbs the whole
powers of man, and that those given up to dissipation
could never attain an exalted position.

CHAPTER V.

Happy married state.

IT is one of the falsest and most pernicious of preju-
dices, that marriage is an invention merely political and
conventional. It is much rather one of the most essen-
tial parts of the destination of man, both for the individ-
ual and the whole ; and an establishment absolutely
necessary for the* education of mankind. By marriage
I understand, a firm, sacred union of two persons, for
the purpose of mutual support, and for giving origin to
and educating children. And, in this intimate union,
founded on so important an object, lies, in my opinion,
the principal grounds of domestic as well as public
felicity; since, in the first place, it is indispensably
requisite for the moral perfection of mankind. By this
close connection of two beings, this association of one's
interest with that of another, is selfishness, the most
dangerous enemy of all virtue, best subdued ; and man
always more inclined to humanity and compassion for
his fellow-creatures, and still brought nearer to his true
state of moral exaltation. His wife and his children
form an indissoluble bond, which unites him to the rest
of mankind, and to the good of the whole : his heart is
always warmed by the sweet sensation of matrimonial
and parental tenderness, and defended from that dead-
ening coldness which so easily overcomes the man who

HAPPY MARRIED STATE. 247

leads a solitary life ; and the endearing cares of a father
impose on him duties which accustom him to order,
industry, and habits of prudence. His passion for the
sex is thereby ennobled, and, from a mere animal in-
stinct, converted into one of the highest moral motives
of action, and violent passions, ill-humor, and bad cus-
toms, are thus best eradicated. Hence arises a very
fortunate influence over the whole and the general good ;
so that I can, with perfect confidence, affirm, that happy
marriages are the most important supports of a State,
and of public peace and felicity. A bachelor always
remains a mere egotist ; restless and unsteady, a prey
to selfish humors and passions ; less interested for
mankind, for his country, and the State, than for himself.
He is overcome by a false sentiment of liberty, which
prevents him from entering into wedlock ; and this
sentiment is still nourished and strengthened by the
condition in which he lives. What can tend more to
produce a fondness for change, sedition, and revolutions,
than an increase of unmarried citizens ? How different
is the case with the married ! That dependence on the
other half, necessary in marriage, accustoms one con-
tinually to a dependence on the laws ; regard for one's
wife and children obliges one to be regular and indus-
trious : by his children, a man is attached closely to the
State ; its interest and prosperity by these means be-
come his own; or, as Bacon expresses it, he who is
married and has children, has given pledges to the State :
he is a bondsman, a true citizen, and a real patriot.
But, what is still more, a foundation is here laid, not
only for the happiness of the present generation, but
for that of the future also ; as it is the matrimonial

248 MEANS WHICH PROLONG LIFE.

union only that produces to the State good moral citi-
zens, accustomed from their youth to regularity and an
observance of their duty. One must not imagine that
the State itself can supply this formation of the manners,
this education which all- wise Nature hath connected with
the hearts of a father and a mother.

I shall now return to my principal object, to point
out the beneficial influence which marriage has on the
physical good of mankind. With the utmost propriety
may it be classed among those means which tend to
prolong life ; and my reasons are as follow :

1st. Marriage is the only means to regulate love, and
to direct it to its proper object. It equally prevents
dissipation, and cold and unnatural indifference. How-
ever much I have recommended continence in youth,
convinced that it is indispensably necessary to promote
long life, I am convinced also that there are certain years
of manhood when it is as prejudicial to suppress by vio-
lence the propensities of nature, as it is to yield to them
before the proper period. It is required by the general
law of harmony. No power in us must remain totally
unexpanded ; each must be exercised in moderation.

2nd. We are told by experience, that all those who
attained to a very remarkable age were married.

3rd. The married state promotes domestic joy, which
is the purest, the most uniform, and the least wasting of
all. It is undoubtedly that which is best suited to
physical as well as moral health, and which can, with
the greatest certainty, preserve the mind in that happy
mean state most favorable to longevity. It tends to
moderate overstrained hope and enthusiastic speculation,
as well as excessive care. Every thing, by the par-

HAPPY MARRIED STATE. 249

ticipation of another being, by the intimate connection
of our existence with that of another, is rendered milder
and more supportable. To this may be added, that
tender charge, that heaven on earth, secured by nothing
so much as wedded love, which lies in the possession of
healthful and well-educated children ; that actual reno-
vation, reserved for us by their company, of which
Cornaro, at the age of eighty, has given so affecting a
picture.

We go out of the world by the same changes almost
as those by which we enter it. We begin as children ;
as children we leave off. We return, at last, to the
same weak and helpless condition as our first. We
must have people to lift us, to carry us, to provide us
nourishment, and even to feed us. We again have need
of parents. And how wise the establishment ! We
find them again in our children, who now take delight
in repaying a part of that kindness which we showed to
them. Children now step, as it were, into the place of
parents, while our weakness transposes us into the
place of children. The venerable oak, on the other
hand, does not enjoy the benefit of such a wise regula-
tion. The old decayed trunk stands alone and for-
gotten, and in vain endeavors to procure from foreign
aid that support and assistance which can be the work
only of natural affection and the bonds of nature.

Do what thou canst, exert thy utmost power ;
Yet still alone thou'lt stand till thy last hour,
When Nature's hand, almighty and divine,
To the grand whole thy lifeless mass shall join.

SCIIILLBK.

CHAPTER VI.

Sleep.

I HAVE already shown that sleep is one of the wisest
regulations of Nature, to check and moderate, at fixed
periods, the incessant and impetuous stream of vital
consumption. It forms, as it were, stations for our
physical and moral existence ; and we thereby obtain
the happiness of being daily reborn, and of passing
every morning, through a state of annihilation, into a
new and refreshed life. Without this continual change,
this incessant renovation, how wretched and insipid
would not life be; and how depressed our mental as
well as physical sensation ! The greatest philosopher
of the present age says, therefore, with justice : Take
from man hope and sleep and he will be the most
wretched being on earth.

How unwisely then do those act who imagine that by
taking as little sleep as possible they prolong their ex-
istence. They obtain their end neither in intensive nor
extensive life. They will, indeed, spend more hours
with their eyes open ; but they will never enjoy life in
the proper sense of the word, nor that freshness and
energy of mind which are the certain consequences of
sound and sufficient sleep, and which stamp a like char-
acter on all our undertakings and actions.

But sufficient sleep is necessary, not only for inten-

RESTORATIVE POWER OF SLEEP. 251

sive life, but also for extensive, in regard to its support
and duration. Nothing accelerates consumption so
much, nothing wastes us so much before the time, and
renders us old, as a want of it. The physical effects of
sleep are, that it retards all the vital movements, col-
lects the vital power, and restores what has been lost
in the course of the day ; and that it separates from us
what is useless and pernicious. It is, as it were, a
daily crisis, during which all secretions are performed
in the greatest tranquillity, and with the utmost per-
fection.

Continued watching unites all the properties destruc-
tive of life ; incessant wasting of the vital power and of
the organs, acceleration of consumption, and prevention
of restoration.

We must not, however, on this account, believe that
too long continued sleep is one of the best means for
preserving life. Long sleep accumulates too great an
abundance of pernicious juices, makes the organs too
flaccid and unfit for use, and in this manner can shorten
life also.

In a word, no one should sleep less than six, nor
more than eight hours. This may be established as a
general rule.

To those who wish to enjoy sound and peaceful re-
pose, and to obtain the whole end of sleep, I recom-
mend the following observations :

1st. The place where one sleeps must be quiet and
obscure. The less our senses are acted upon by exter-
nal impressions, the more perfectly can the soul rest.
One may from this see how improper the custom is of

252 MEANS WHICH PROLONG LIFE.

having a candle burning in one's bed-chamber during
the night.

2nd. People ought always to Deflect, that their bed-
chamber is a place in which they pass a great part of
their lives ; at least they do not remain in any place so
long in the same situation. It is of the utmost impor-
tance, therefore, that this place should contain pure
sound air. A sleeping apartment must, consequently,
be roomy and high ; neither inhabited nor heated dur-
ing the day ; and the windows ought always to be kept
open, except in the night time.

3d. One should eat little, and only cold food for sup-
per, and always some hours before going to bed.

4th. When abed, one should lie not in a forced or
constrained posture, but almost horizontal; the head
excepted, which ought to be a little raised. Nothing is
more prejudicial than to lie in bed half-sitting. The
body then forms an angle ; circulation in the stomach
is checked, and the spine is always very much com-
pressed. By this custom one of the principal ends
of sleep, a free and uninterrupted circulation of the
blood, is defeated ; and, in infancy and youth, deform-
ity and crookedness are often its consequences.

5th. All the cares and burden of the day must be
laid aside with one's clothes ; none of them must be car-
ried to bed with us ; and, in this respect, one by custom
may obtain very great power over the thoughts. I am
acquainted with no practice more destructive than that
of studying in bed, and of reading till one falls asleep.
By these means the soul is put into too great activity,
at a period when every thing conspires to allow it per-

RESTORATIVE POWER OF SLEEP. 253

feet rest ; and it is natural that the ideas, thus excited,
should wander and float through the brain during the
whole night. It is not enough to sleep physically;
man must sleep also spiritually. Such a disturbed
sleep is as insufficient as its opposite, that is, when
our spiritual part sleeps, but not our corporeal : such,
for example, as sleep in a jolting carriage on a journey.
6th. One circumstance, in particular, I must not here
omit to mention. Many believe that it is entirely the
same if one sleeps these seven hours either in the day
or the night time. People give themselves up, there-
fore, at night, as long as they think proper, either to
study or pleasure ; and imagine that they make every
thing even when they sleep in the forenoon those hours
which they sat up after midnight. But I must reqaest
every one, who regards his health, to beware of so se-
ducing an error. It is certainly not the same, whether
one sleeps seven hours by day or by night ; and two
hours sound sleep before midnight are of more benefit
to the body than four hours in the day. My reasons
are as follow :

KThat period of twenty-four hours, formed by the
regular revolution of our earth, in which all its inhabi-
tants partake, is particularly distinguished in the physi-
cal economy of man. This regular period is apparent
in all diseases ; and all the other small periods, so won-
derful in our physical history, are by it in reality deter-
mined. It is as it were, the unity of our natural
chronologyj Now, it is observed, that the more the
end of these periods coincides with the conclusion of
the day, the more is the pulsation accelerated : and a
feverish state is produced, or the so called evening

254 MEANS WHICH PROLONG LIFE.

fever, to which every man is subject. The accession
of new chyle to the blood, may, in all probability, con-
tribute something towards this fever, though it is not
the only cause ; for we find it in sick people who have
neither eat nor drunk. It is more owing, without
doubt, to the absence of the sun, and to that revolution
in the atmosphere which is connected with it. This
evening fever is the reason why nervous people find
themselves more fit for labour at night than during the
day. To become active, they must first have an arti-
ficial stimulus ; and the evening fever supplies the place
of wine. But one may easily perceive that this is an
unnatural state ; and the consequences are the same as
those of every simple fever: lassitude, sleep, and a
crisis, by the perspiration which takes place during that
sleep. It may with propriety therefore be said, that all
men every night have a critical perspiration, more per-
ceptible in some, and less so in others, by which what-
ever useless or pernicious particles have been imbibed
by our bodies, or created in them, during the day, are
secreted and removed. This daily crisis, necessary to
every man, is particularly requisite for his support;
and the proper period of it is when the fever has at-
tained to its highest degree, that is, the period when
the sun is in the nadir, consequently midnight. What
do those, then, who disobey this voice of Nature which
calls for rest at the above period, and who employ this
fever, which should be the means of secreting and puri-
fying our juices to enable them to increase their
activity and exertion? By neglecting the critical
period, they destroy the whole crisis of so much im-
portance ; and, though they go to bed towards morning,

PROPER PERIOD OF SLEEP. 255

cannot certainly obtain, on that account, the full benefit
of sleep, as the critical period is past. They will never
have a perfect, but an imperfect crisis ; and what that
means is well known to physicans. Their bodies also
will never be completely purified. How clearly is this
proved by the infirmities, rheumatic pains, and swollen
feet, the unavoidable consequences of such lucubration.

Besides, the eyes suffer more by this custom; for
one labors then the whole summer through with candle-
light, which is not necessary for those who employ
the morning.

And, lastly, those who spend the night in labor, and
the morning in sleep, lose that time which is the most
beautiful and the best fitted for labor. After every
sleep we are renovated in the properest sense of the
word ; we are, in the morning, always taller than at
night ; we have then more pliability, powers, and
juices ; in a word, more of the characteristics of youth ;
while, at night, our bodies are drier and more ex-
hausted, and the properties of old age then prevail.
One, therefore, may consider each day as a sketch,
in miniature, of human We, in which the morning
represents youth ; noon, manhood ; and evening, old
age. Who would not then employ the youthful part
of each day for labor, rather than begin his work in
the evening, the period of old age and debility ? In
the morning, all nature appears freshest and most en-
gaging ; the mind at that period is also clearest, and
possesses most strength and energy. It is not, as at
night, worn out, and rendered unequal, by the multi-
farious impressions of the day, by business and fatigue :
it is then more original, and possesses its natural

256 MEANS WHICH PROLONG LIFE.

powers. This is the period of new mental creation,
of clear conceptions and exalted ideas. Never does
man enjoy the sensation of his own existence so purely
and in so great perfection as in a beautiful morning.
He who neglects this period, neglects the youth of his
life.

All those who attained to a great age were fond of
early rising ; and John Wesley, the founder of the
Methodists, an original and singular man, was so
convinced of the necessity of this custom, that he
made it a point of religion to get up early, and by
these means lived to the age of eighty-eight. His
motto, which as a true maxim of life I shall here re-
commend, was :

To go early to bed, and early to rise,

Will make a maa healthy, wealthy, and wise.

CHAPTER VII.

Bodily exercise.

" WHEN I consider the physical structure of man,"
said the great Frederick, " it appears to me as if Nature
had formed us rather to be postillions than sedentary
men of letters." And, without doubt, though this ex-
pression be strong, it contains a great deal of truth.
Man is, and always remains, a middle being, that
incessantly fluctuates between the brute and the angel ;
and as much as he would deviate from his higher des-
tination, did he continue the mere animal, as much
does he offend against his present destination when he
wishes to be merely spirit to think only and to per-
ceive. He must exercise his animal and spiritual
powers in the like degree, if he be desirous to accom-
plish perfectly the object for which he was created ;
and this, in regard to the duration of life, is of the
utmost importance. Harmony in the movements is
the grand foundation on which health, uniformity of
restoration, and the duration of the body, depend ; and
these certainly cannot take place if we merely sit and
think. The propensity to bodily movement is, in man,
as great as the propensity to eating and drinking. Let
us only look at a child. Sitting still is to it the great-
est punishment. And the faculty of sitting the whole
day, and not feeling the least desire for moving, is cer-
17

258 MEANS WHICH PROLONG LIFE.

tainly an unnatural and diseased state. We are taught
by experience, that those men attained to the greatest
age, who accustomed themselves to strong and inces-
sant exercise in the open air.

I consider it, therefore, as an indispensable law of
longevity, that one should exercise, at least, an hour
every day, in the open air. The most healthful time
is before meals, or from three to four hours after.

In this respect, besides small journeys, and excur-
sions on horseback, moderate dancing, and other gym-
nastic exercises are of great service : and it is much to
be wished that we here paid more attention to imitate
the ancients, who managed scientifically this promoter
of health, and suffered no external circumstances to
prevent them from using it. It is of most benefit when
not merely the body, but the soul also, is exercised and
kept awake at the same time. A walk, therefore, to
answer fully its object, must be directed to a quarter
where the prospects are always agreeable, and to a
certain term or spot.

CHAPTER VIII.

The enjoyment of free air. Moderate temperature of warmth.

THE enjoyment of free air may be considered as a
nourishment equally necessary for our existence as
eating and drinking. Pure air is certainly the great-
est means of strengthening and supporting life ; while
confined and corrupted air is its most subtle and deadly
poison.

From this may be deduced the following practical
rules :

1st. Suffer no day to pass without enjoying the pure
open air beyond the boundaries of a town or city
Consider your walk not merely as the means of ex-
ercise, but, in a particular manner, as the enjoyment
of the purest vital nourishment, which is indispensably
necessary above all to those who are much confined
to their apartments. Besides this advantage, one ob-
tains that also of making one's self, by such daily en-
joyment of air, acquainted and familiar with a free
atmosphere ; and people are thus secured against one
of the greatest evils that usually afflict mankind, I
mean too much sensibility in regard to all impressions
and variations of the weather. This is one of the
most abundant sources of disease ; and there is no
other method of counteracting it, but to harden one's
self by daily exposure to the open air.

260 MEANS WHICH PROLONG- LIFE.

Lastly. By this custom one will obtain infinite ad-
vantage in regard to the eyes ; for it is certain that a
great cause of weak eyes and short-sightedness are
the four walls within which we are accustomed to live
from our infancy, and by which the eyes at length
lose their whole power of seeing remote objects dis-
tinctly. The best proof of this is, that such weakness
of the eyes is to be found only in cities, and not in the
country.

2nd. One should endeavor, wherever it is possible,
to live high. Those who have a regard for their health,
at least in cities, ought not to inhabit the ground-floor.
Let the windows be opened daily. Ventilators, or
chimneys, are the best means for purifying the foul
atmosphere of confined apartments. People ought
not to sleep in rooms which have been inhabited the
whole day ; and the windows of bed-chambers should
be always kept open in the daytime.

I must here add one remark of the utmost impor-
tance for the prolongation of life. The air in which
one lives should be kept in a moderate degree of tem-
perature. It is much better to live in air too cool
than too hot ; for heat accelerates, in an extraordinary
degree, the stream of vital consumption, as is proved
by the shorter lives of those who inhabit warm coun-
tries ; and many people create artificially such a cli-
mate by means of their hot apartments. The tempe-
rature of the air in an apartment should never exceed
66 of Fahrenheit's thermometer.

CHAPTER IX.

Rural and country life.

FORTUNATE are they to whose lot it has fallen to
remain near and true to their parent Earth ; and to
find their happiness, labor, and destination in immedi-
ate intercourse with Nature. They reside at the real
source of eternal youth, health, and felicit ; both body
and soul enjoy there the utmost harmony and well-
being. Simplicity, cheerfulness, innocence, and con-
tentment, accompany them through life; and they
attain to the utmost term which it is capable of reach-
ing with its present organization. I cannot refrain,
therefore, from inserting here what Herder has said on
this subject :

The resolution of my friend to change
His walled prison for a rural seat
I much applaud why should we foolishly
Pile up in lofty towers the hard hewn rock ?
To fright us with their sudden fall, or hide
From our dark eyes e cheering face of heaven !
Not so in former days lived the young world,
In innocence and peace ; free from such folly,
'Midst rural scenes there harmless mirth prevails,
And fills the breast with never-ceasing joy :
There we behold the wide-expanded heaven ;
No neighbor robs us of the light of day ;

262 MEANS WHICH PROLONG LIFE.

And from the clear fresh spring Apollo bids ua

Assuage our thirst with his own liquor.

O did but men know what is happiness !

Our mother Nature ne'er within dark cities,

Or gloomy walls and castles, it confined.

It on the plain blooms equally for all.

Those find it oft who seek it not ; and he

Who spurns base ore will it enjoy his treasure

Is what the earth presents in the bright stream

He sees his silver ; and his gold shoots up

In yellow corn, or smiles from fruitful trees.

He hears his concert in the shady grove ;

And there his chorus, free at will to range,

Joins in the mirthful or the pensive strain.

Far otherwise within the town confined :

The captive songster in its cage complains !

The slave who feeds it thinks it sings alone

To please its master ; but with every note

It bids its tyrant give it liberty

Nature delights in rural scenes : and Art,

Her imitator, there must follow her

With timid steps. Of foliage ever green

Behold yon palace, arched with thick woven boughs !

Where thou mayst sit, like Persia's boasted lord

In halls of cedar and 'midst peace enjoy,

What he ne'er knows, sound, sweet, refreshing sleep.

Great cities are great plagues ! There native joy

Flies from man's breast, and makes him pleasure seek

In Art alone there every thing by paint

Is seen disguised the countenance and walls

Each action, word, and even the very heart

All there consists of costly wood or stone ;

And even the owners seem as hard as these.

O rural life, 'midst poverty how rich !

When hunger bids, there thou mayst nobly feast

On what each season for thy use brings forth,

In rich variety. The plough thy table ;

And a green leaf, by way of dish, supports

RURAL AND COUNTRY LIFE. 263

Thy meal of fruit. A homely wooden jug
Draws up refreshing drink from the pure stream,
Which, free from poison, pours out health alone,
And with soft murmur thee to sleep invites :
"While, in the air, the lark high-soaring sings
Now mounting up, again descending low
Until, at length, it drops into its nest,
Just at thy foot, between two furrows placed.

If one, indeed, be desirous of sketching out, accord-
ing to theoretical principles, the idea of a life condu-
cive to health and longevity, one must recur to that
presented to us by a country life. Nowhere are all the
requisites for that purpose so perfectly united as here ;
and nowhere does every thing in and around mankind
labor so powerfully to promote health and longe/ity.
The enjoyment of pure, sound air ; simple and frugal
food ; daily and strong exercise without doors ; estab-
lished regularity in all the vital operations ; the beauti-
ful prospect of simple Nature ; and a frame of internal
peace, cheerfulness, and serenity, which by these means
are diffused throughout the mind what sources of
vital restoration ! Besides, a country life is, in a par-
ticular manner, capable of giving that disposition which
is contrary to the passionate, overstrained, and eccen-
tric ; and the more so as it removes us from the dissipa-
tion, corruption, and worthlessness of the town, which
tend always to nourish the passions. It consequently
preserves, both internally and externally, peace of
mind and equanimity, which are such great supports to
life. It inspires us with cheerfulness and hope, and
increases our enjoyments in general, but without vio-
lence or passion, and moderated by the softest tone of

264 MEANS WHICH PROLONG LIFE.

Nature. It needs excite no wonder, then, that, accord-
ing to experience, instances of the greatest age are to
be found in rural life only.

It is a melancholy reflection, that this kind of life,
the earliest and most natural state of man, should at
present be so little esteemed that the fortunate farmer
even quits it till his son becomes a studious rake ; and
the proportion between countrymen and citizens seems
daily to be diminished. It certainly would be much
better for the happiness of individuals, as well as of the
whole, if the greater part of the penknives and scissors
now in use were converted into ploughshares, and that
those hands occupied in scribbling were employed with
the plough and the spade. The former, to many, is
indeed only labor of the hands ; but the latter is the
most useful, and, if I am not much mistaken, we shall
be at length obliged, from political considerations, to
recur to it once more. Man must again approach
nearer to his parent Earth, from which he has so far
removed in every point of view.

All, indeed, cannot be farmers by profession ; but
how beneficial would it be, if men of letters, people of
business, and those who labor with their heads, would
divide their time between both kinds of employment;
and imitate the ancients, who, notwithstanding their
philosophical or political engagements, did not think it
beneath their dignity to devote their spare hours to
agriculture, and to rusticate in the proper sense of the
word ! All the melancholy consequences of a seden-
tary life, and overstraining the mental faculties, would
disappear, if people, some hours every day, or a few
mouths in the year, would take hold of a spade or a

mattock and cultivate their field or their garden ; for
the usual method of living in the country, (which in
general means nothing else than to carry along with
one care and books, and to read, think, or write in the
open air, instead of a chamber,) cannot accomplish that
object. Such rustication will again restore the equi-
librium between the mind and the body, which the
writing-desk so often destroys. By an union of these
three grand panaceas, exercise, free air, and exhilarat-
ing the spirits, a renovation and restoration may be
annually effected, which will be of incredible service to
vital duration and happiness. Nay I do not think I say
too much when I promise, from this practice, besides
physical advantages, many of a spiritual and moral
nature also. Cobwebs of the brain and hypotheses of
the closet will certainly be less abundant ; people will
not so often imagine the whole world to be contained
in their persons, or within the four walls of their studies,
and treat it in that point of view ; and the mind will
acquire a greater propensity to truth, more soundness,
more warmth, and a more natural manner of thinking,
properties which distinguish the Greek and Roman
philosophers so much, and for which, in my opinion,
they were indebted principally to their continual inter-
course with Nature. One ought therefore to be exceed-
ingly careful never to suffer a taste for Nature to be
extinguished in the mind. This taste may be easily
destroyed, by always living recluse, by incessant appli-
cation to business, and by abstract speculations in the
closet ; and when it is once lost, the most beautiful
rural scenes will have no effect upon us ; and one, in
the most delightful districts, and under the serenest

266 MEANS WHICH PROLONG LIFE.

sky, may remain in a state of living death. This may
be best guarded against by not removing too long or
too far from Nature ; by quitting, as often as one can,
the artificial and abstract world ; by opening all the
senses to the beneficent influences of Nature ; and if
one from the earliest youth endeavors to acquire a
taste for the study of Natural History (a point which
ought to be attended to in education), and to warm the
imagination for it by the beautiful imitations of paint-
ing, and the heart-exalting descriptions of the poets of
Nature, such as a Zachariii, Thomson, Gesner, Mat-
thison, etc.

CHAPTER X.

Travelling.

I CANNOT possibly omit to devote here a particular
place to this enjoyment, and to recommend it as a
means of prolonging life. The continual motion, vari-
ety of scene, exhilaration of the mind, and the use of
free and changed air, have a magical effect upon man-
kind, and contribute in an incredible degree to renovate
and revive the whole frame. Vital consumption may
indeed be thereby somewhat increased; but this is
amply counterbalanced by the increased restoration
which is effected, partly in regard to the body, by
digestion being strengthened and invigorated, and
partly in regard to the mind, by a succession of agree-
able impressions, and the forgetfulness of one's self.
This help, therefore, I recommend to those whose
employment condemns them to a sedentary life, who
are continually engaged in abstract studies or oppres-
sive labor, whose minds have sunk into a state of insen-
sibility, melancholy or hypochondriasis, or, what is
worst of all, are strangers to domestic felicity.

But as many employ it in such a manner that it pro-
duces no effect, it perhaps may be of some service to
communicate here a few of the most important rules
how people must travel in order to benefit their health
and their life.

268 MEANS WHICH PROLONG LIFE.

1st. Travelling on foot, or rather on horseback, is
the most healthful, and best calculated to answer the
end proposed ; but when one is weakly, or undertakes
long excursions, it is more advisable to travel in a car-
riage.

2nd. When one travels in a carriage, it is very bene-
ficial always to change the posture ; that is, to sit some-
times, and sometimes to recline. By these means one
can best prevent the evils attending continued riding in
this manner, which are occasioned principally by the
jolting being in one direction.

3rd. Nature will not suffer any sudden transitions.
It is therefore improper for people accustomed to a
sedentary life to undertake suddenly a journey during
which they will be exposed to violent jolting. The
case here is the same as if one accustomed to drink
water should all at once begin to drink wine. Let the
transition be slow, and begin with moderate motion.

4th. Excursions, the object of which is health and
the prolongation of life, must not be fatiguing ; but this
can be determined only by difference of temperament
and constitution. Ten or twelve miles daily, with a
rest every three or four days, may perhaps be the best
standard. One ought, above all things, to avoid travel-
ling in the night time; which, by interrupting the
necessary refreshment, checking perspiration, and ex-
posing the body to unhealthful air, is always preju-
dicial. By respecting nocturnal rest, one may accom-
plish twice as much in the day.

5th. People must not imagine that they may indulge
a little more in intemperance when on a journey. One,
however, needs not to be too nice in the choice of food

USES OF TRAVELLING. 269

and drink ; and it is always best to use the common
fare of each country. But at any rate the stomach
ought not to be overloaded. By the motion of travel-
ling, the power of the body is too much divided for the
stomach to admit of a large quantity of food ; and the
motion itself, by these means, will become more fatigu-
ing. People, in particular, should not indulge too
much in heating food and liquors, as is often the case
on journeys; for travelling alone acts as a stimulus,
and less stimulating nourishment is then required than
in a state of rest. A want of attention to this rule may
occasion too violent irritation, inflammation, accumula-
tions of the blood, etc. It is most proper, on journeys,
too eat rather little at a time, but often ; to drink more
than one eats ; and to choose food easy of digesiion,
yet strongly nutritive, not of a heating nature, and such
as cannot be readily adulterated. It is safest, therefore,
in the country, and in small inns, to use milk, eggs,
well-baked bread, boiled or roasted meat, and fruit. I
advise travellers, above all, to be on their guard against
the wine kept in such houses. It will be much better
to drink water with the addition of a little lemon-juice,
or of some good liquor which they may carry along
with them. If the water be impure, it may be ren-
dered sweet by charcoal powder.*

* This is one of the greatest and beneficial discoveries of
modern times, for which we are indebted to Mr. Lowiz of Peters-
burg. Water which has a disagreeable odor, or has become
putrid, may almost immediately be freed from its nauseous taste,
as well as its bad smell, and be converted into good drinkable
liquor, by the following process : Take some burnt charcoal,
and reduce it to a fine powder. Mix about a tablespoonful of

270 MEANS WHICH PROLONG LIFE.

6th. Avoid immoderate exertion and wasting of the
powers. It is, however, as difficult in general to lay
down a proper standard of motion, as of eating and
drinking. But Nature, in this, has given us a very ex-
cellent guide, a sense of lassitude, which is here of as
much importance as the sense of satiety in eating or
drinking. Weariness is nothing else than the voice of
Nature, which tells us that our stock of powers is ex-
hausted, and that he who is tired should enjoy repose.
But Nature may, indeed, become lost in habit ; and we
may be as insensible of lassitude as the continual glut-
ton is of fulness, especially when the nerves are over-
strained by stimulating and heating food and drink.
There are then, however, other signs to tell us that we
have exceeded the proper measure ; and I request that
to these the strictest attention may be paid. When one
begins to be low-spirited or dejected ; to yawn often,
and be drowsy, yet at the same time to be incapable of
sleeping though one enjoys rest ; when the appetite is
lost ; when the smallest movement occasions a fluttering
of the pulse, heat, and even trembling ; when the mouth
becomes dry, and is sensible of a bitter taste, it is high
time to seek refreshment and repose, if one wishes to
prevent illness already beginning to take place.

7th. While one is travelling, insensible perspiration
may easily be checked ; and cold is the principal

this powder in a pint of water, stir it well round, and suffer it to
stand for a few minutes. Let it then run slowly through filter-
ing paper into a glass, and it will be found quite transparent,
without any bad taste or smell, and perfectly pure for drinking.
People may preserve the charcoal powder a long time in a small
bottle well corked, and carry it with them when they travel.

USES OF TRAVELLING. 271

source of those diseases which thence arise. It is
advisable, therefore, to guard against all sudden transi-
tions from heat to cold, or the contrary ; and those who
have great sensibility in the skin, will do well, when
they go on a journey, to carry a thin flannel shirt along
with them.

8th. Cleanliness, when one travels, is doubly neces-
sary ; and, therefore, to wash the body frequently with
cold water is much to be recommended.^ This will con-
tribute also, in a great degree, to remove lassitude.

9th. During winter, or in a cold climate, one may
'always submit to greater exercise than during summer,
or in warm climates, where perspiration exhausts one
half of the strength. One, also, can undergo more
fatigue early in the morning than in the afternoon.

10th. Full-blooded persons, or those who are subject
to a spitting of blood, or other serious disease, must
consult their physician before they undertake a journey.

CHAPTER XI.

Cleanliness, and care of the skin.

BOTH these I consider as important means for the
prolongation of life. Cleanliness removes every thing
that Nature has secreted from us, as useless or cor-
rupted ; as well as every thing prejudicial, that might
be conveyed to us, from without, through the super-
ficies of our bodies.

Care of the skin is an essential part of cleanliness,
and consists in paying such attention to it from infancy,
that it may be kept in a lively, active, and useful con-
dition.

The skin, indeed, must not be considered merely as
a common covering to defend us from the sun and the
rain, but as one of the most important organs of our
body, without the incessant activity and agency of
which there can be neither health nor long life ; and
in the neglect of which, in modern times, lies the secret
source of numberless diseases and evils that tend to
shorten our existence. May the following observa-
tions, therefore, make more impression on my readers,
and excite more attention to this organ and the man-
agement of it !

The skin is the greatest medium for purifying our
bodies; and every moment a multitude of useless,
corrupted, and worn-out particles evaporate through

CARE OF THE SKIN. 273

its numberless small vessels, in an insensible manner.
This secretion is inseparably connected with life, and
the circulation of our blood ; and by it the greater
part of all the impurity of our bodies is removed. If
the skin, therefore, be flabby or inactive, and if its
pores be stopped up, an acridity and corruption of
our juices will be the unavoidable consequence, and
the most dangerous diseases may ensue.

Besides, the skin is the seat of feeling, the most
general of all our senses, or that which in an essential
manner connects us with surrounding Nature, and in
particular with the atmosphere ; and by the state of
which, in a great measure, the sensation of our own
existence, and the relation which we bear to every
thing around us, is determined. Hence a greater or
less sensibility, in regard to disease, depends very
much on the skin ; and those whose skin is weak or
relaxed have generally a sensation too delicate and
unnatural, by which means it happens that they are
internally affected in a manner highly disagreeable,
by every small variation in the weather, every change
of the atmosphere, and at length become real baro-
meters. Such a constitution is called the rheumatic,
and arises chiefly from a want of strength in the skin.
It occasions a tendency to perspiration, which is also
an unnatural state, and which exposes us continually
to colds and other disorders.

It is, likewise, a grand means for preserving an equi-
librium in the powers and motion of our bodies. The
more active and open the skin is, the more secure will
people be against obstructions, and diseases of the
lungs, intestines, and lower stomach ; and the less ten-
18

274 MEANS WHICH PROLONG LIFE.

dency will they have to gastric (bilious) fevers, hypo-
chondriasis, gout, asthma, catarrh, and varicose veins.
One great cause of these disorders being at present so
common amongst us, is, that we no longer endeavor
to cleanse and strengthen the skin by bathing and other
means.

. The skin, moreover, is one of the most important
means of restoration of our bodies, by which a multi-
tude of fine spiritual component parts are conveyed to
us from the atmosphere. Without a sound skin there
can be no complete restoration, which is one of the
chief principles of long life.

It ought also not to be forgotten, that the skin is the
grand organ of crises, that is to say, the assistant of
Nature in disease ; and that a man with open pores,
and a skin sufficiently vigorous, may depend on being
cured much more easily and with more certainty, and
often even without the use of medicine.

That such an organ must be a great support of
health and life, no one will deny ; and it is therefore
incomprehensible how people in modern times, since
mankind have become more enlightened, should neg-
lect it so much. Nay, we in general find, that, instead
of paying the least attention to it, they from their in-
fancy do every thing in their power, as it were, to re-
lax and to weaken it, and to stop up its pores. The
most of mankind, except at baptism, never experience
the benefit of bathing during their whole lives ; the skin
by dirt and daily perspiration is more and more stopped
up ; weakened and relaxed by warm clothing, furs,
feather-beds, etc. ; rendered inactive by confined air,
and a sedentary life j and I think I may, without ex-

CARE OF THE SKIN. 275

aggeration, assert, that, among the greater part of
men, the pores of the skin are half-closed and unfit
for use.

Let me here be permitted to call the attention of my
readers to an incongruity, which is not the only one of
the kind in human life. The most ignorant person is
convinced that proper care of the skin is indispensably
necessary for the existence and well-being of horses
and various animals. The groom often denies himself
sleep, and other gratifications, that he may curry and
dress his horses sufficiently. If they become meagre
and weak, the first reflection is, whether there may not
have been some neglect or want of care in regard to
combing them. Such a simple idea, however, never
occurs to him in respect to his child. If it grow feeble
and sickly ; if it pine away and is afflicted with disease,
the consequence of dirt, he thinks rather of witchcraft
and other absurdities than of the real cause, neglecting
to keep the skin pure and clean. Since we show so
much prudence and intelligence in regard to animals,
why not in regard to men ?

The rules which I have to propose for preserving
cleanliness and a sound state of the skin, are remark-
ably easy and simple ; and, if observed from youth,
may be considered as very powerful means for the
prolongation of life.

1st. Remove carefully every thing that the body
has secreted as corrupted or prejudicial. This may
be done by changing the linen often, daily if it be
possible, and also the bed-clothes, or at least the sheets ;
by using, instead of a feather-bed, a mattress, which

276 MEANS WHICH PROLONG LIFE.

attracts less dirt ; and by continually renewing the air
in apartments, and particularly in one's bed-chamber.

2nd. Let the whole body be washed daily with cold
water, and rub the skin strongly at the same time,
by which means it will acquire a great deal of life and
vigor.

3rd. One ought to bathe once a week, the whole
year through, in tepid water; and it will be of con-
siderable service to add to it three or four ounces of
soap. It is much to be wished that public baths were
again erected, that poor people might enjoy this benefit,
and thereby be rendered strong and sound, as was the
case some centuries ago.*

I cannot quit this subject without mentioning sea-

* Traces of this laudable practice may still everywhere be
seen in the remains of baths and bathing-houses ; but the use of
it has been abandoned through the inconceivable indolence of
mankind. Every Sunday evening, people formerly went in pro-
cession through the streets, beating on basins, to remind the
lower classes of bathing; and the tradesman, who labored at
dirty work, washed off, in the bath, that dirt which now adheres
to him perhaps during his whole life. In every place of any
consequence there should be a bathing-house, or a floating bath
on some river for the summer, and another for the winter. In
bathing it ought to be a rule never to enter the water with a full
stomach, but either fasting or four hours after eating ; never to
bathe when the body is hot ; to remain in cold water not more
than a quarter of an hour, and in warm water never more than
three quarters ; to be cautious of catching cold when one comes
out, which may be best done by putting on a flannel gown ; and
during dry warm weather, to take moderate exercise afterwards ;
but in cold, inoist weather, to remain for an hour in a warm
apartment.

CAKE OF THE SKIN. 277

bathing, which, on account of its stimulative and pene-
trating power, may be placed at the head of those
means that regard the care of the skin ; and which
certainly supplies one of the first wants of the present
generation, by opening the pores, and thereby reinvig-
orating the whole nervous system. This bathing is
attended with two important advantages. The first
is, that besides its great healing power, in cases of
disease, it may be employed by those who are perfectly
well, as the means most agreeable to Nature for strength-
ening and preserving health ; which is not the case
with a great many other kinds of bathing, that are in-
jurious to a healthy person. In this respect it may
be compared to bodily exercise, which can remove dis-
eases otherwise incurable, and which may be used
also by those who are sound, in order to preserve them-
selves in that state. The other advantage is the noble,
grand, and indescribable prospect of the sea connected
with it ; and which, on those not acquainted with it,
has an effect capable of bracing up the nervous system,
and producing a beneficial exaltation of the whole
frame. I am fully convinced that the physical effects
of sea-bathing must be greatly increased by this impres-
sion on the mind ; and that a hypochondriac or nervous
person may be half cured by residing on the sea-coast,
and enjoying a view of the grand scenes ,of Nature
which will there present themselves : such as the rising
and setting of the sun over the blue expanse of the
waters, the awful majesty of the waves during a storm,
etc. For the like purpose, therefore, I would advise
an inhabitant of the inland parts to take a journey to

278 MEANS WHICH PROLONG LIFE.

the sea ; and an inhabitant of the coast to make an ex-
cursion to the Alps ; for both, in my opinion, are the
sublimest productions of Nature. The thanks of the
public are undoubtedly due to that exalted prince, so
much a friend to mankind, who erected the first sea-
bath in Germany, at Dobrahn, near Rostock ; and to
that worthy physician Vogel, who formed the plan of
it in a manner so excellent and so likely to make it
answer the intended purpose, and who assists its salu-
tary effects by his presence and advice.

4th. People should wear warm clothing that does
not tend to weaken the skin, and which may readily
suffer the perspiring matter to pass through it. In
this respect, I know nothing more prejudicial than to
wear fur, which, by its great warmth, weakens the
skin very much; does not promote evaporation, but
sweat ; and, on account of the thickness of the leather,
does not suffer the perspiring particles to fly off. The
consequence is, that a continual vapor-bath is formed
between the fur and the skin, and that a great part of
the impure matter is again thrown back on the body,
and imbibed by it Far better is flannel, which has
the advantage of fur, without the disadvantage of at-
tracting dirt and occasioning too much heat. But all
these warm coverings on the bare skin are to be recom-
mended only during intense cold or for weakly people
subject to rheumatism. In infancy and youth, and
for those whose bodies are sound, it is far preferable
to wear next the skin either linen or cotton, with" a
vest of the same in summer, and in winter one of wool-
len.

5th. One should use much bodily exercise ; for this
is a great promoter of insensible perspiration.

6th. Avoid all food unfavorable to perspiration.
Of this nature is fat of every kind, pork, goose,
cheese, etc.

CfiAPTEB, XII.

Proper food. Moderation in eating and drinking. Preservation of
the teeth.

THE idea of proper regimen is somewhat relative.
In general, we find that those men who were not too
nice or particular in regard to their food, but who lived
sparingly, attained to the greatest age ; and it is an
advantage peculiar to man, that he can digest and
assimilate the most heterogeneous kinds of nourish-
ment, and is not, like other animals, confined to one
certain class. It is proved that people in a natural
state, who are much exposed to the free open air and
to exercise, require few rules respecting their diet. It
was our artificial manner of living that first rendered
regimen necessary.

It is at any rate certain, that the prolongation of life
does not so much depend on the quality, as on the
quantity, of our nourishment ; and the instance of
Cornaro affords an astonishing proof how far a man of
weakly constitution may thereby prolong his existence.

It may with truth be asserted, that the greater part
of mankind eat more than is necessary ; and by being
crammed and over-fed in infancy, we are deprived of
that natural sensation which ought to tell us when we
have enough.

CAKE OF THE TEETH. 281

I shall here only give such common rules in regard
to eating and drinking as will suit the generality of man-
kind ; and which, I am convinced, will have an essen-
tial influence in prolonging life.

1st. It is not what we eat, but what we digest, that
does us good, and serves to nourish our bodies. He
who wishes to live long ought, therefore, to eat slowly;
as our food must obtain in the mouth the first degree of
preparation and assimilation. This is effected by its
being sufficiently chewed and mixed with saliva ; botli
which I consider as a principal part of the business of
restoration, and consequently set great value upon them
in regard to the prolongation of life, especially as it ap-
pears by my researches that all those who were accus-
tomed to eat slowly attained to a great age.

2nd. A great deal depends on good teeth ; and, there-
fore, I can with propriety reckon preservation of the
teeth among those means that tend to prolong life. By
the following rules, if observed from infancy, the teeth
may be preserved fast and sound to the greatest age.

One must always join with the flesh used for food a
sufficient quantity of vegetables and bread; for flesh
adheres more readily between the teeth, and tends to
injure them. It will be found, therefore, that those
who use little or no flesh, boors and country people,
have always the best teeth, though they never clean
them. But no tooth-powder can be more efficacious
than a piece of dry burnt bread ; and it is a custom
very salutary for the teeth, to chew slowly a crust of
bread after every meal.

Avoid exposing the teeth to a sudden transition from
heat to cold, or the contrary ; for the teeth are covered

282 MEANS WHICH PROLONG LIFE.

with a glassy kind of enamel, which may be easily
cracked by such sudden changes ; so that corrupted par-
ticles can insinuate themselves into the rents, and lay the
first foundation of decay within them. It will be best,
therefore, never to take too hot or too cold things into
the mouth ; and be careful, above all, not to drink cold
liquor while you are eating warm food, such as hot
soup, etc.

Never eat sugar, and avoid confections, which are
mixed with a great deal of tough calcareous particles.

As soon as you observe that a tooth is decayed, have
it immediately pulled out, otherwise it will infect the
rest.*

Wash your teeth with water every morning, and in
particular after each meal. This will remove any re-
mains of food adhering to them, which commonly fix
themselves between the teeth, and lay the first ground
for decay.

Those who observe these rules will seldom have oc-

* It is an error to suppose that a decayed tooth has the power
of infecting its neighbor, and it is bad advice to suggest its ex-
traction. One of the chief agents of destruction of the teeth is
pressure, therefore a tooth usually decays on the side which is
contiguous to another, and as in all probability both teeth are
sufferers from the pressure, both are liable to decay : because one
precedes the other in this action, it has been inferred that the de-
cayed tooth has contaminated its fellow, but this is not the fact.
Then as to the advice. When a tooth has decayed, the patient
should seek the dentist, who will probably clear out the dead
part, and stop the cavity with gold. When this operation is well
and judiciously performed^ the tooth will last as long as if it
were perfectly sound. Hence, the chief art of the dentist of the
present day is to save the teeth and not waste them, as was the
case when our author nourished. EDITOR.

CARE OF THE TEETH. 283

casion for tooth-powder. But if th^ teeth have a ten-
dency, as is the case naturally in some men, to become
foul, or to acquire what is called tartar, I recommend
the following harmless prescription : Take half an
ounce of red sandal-wood, with a quarter of an ounce of
China-root (similax aspera Ghinensis) ; reduce them to
a fine powder, and sift it through a hair-sieve.* Then
add to it six drops of the oil of cloves, and the same
quantity of bergamot oil ; and rub the teeth with it in
the morning.

3rd. Beware of studying, reading, or straining the
head while at table. That period must certainly be
consecrated to the stomach. It is the time of its gov-
ernment ; and the mind must no further interfere with
it than may be. necessary to assist its operations.
Laughter is one of the greatest helps to digestion with
which I am acquainted ; and the custom, prevalent
among our forefathers, of exciting it at table by jesters
and buffoons, was founded on true medical principles.
In a word, endeavor to have cheerful and merry com-
panions at your meals. What nourishment one re-
ceives amidst mirth and jollity, will certainly produce
good and light blood.

4th. Do not expose yourself to violent motion after
meals; for this will disturb, in an astonishing degree,

* This tooth-powder, composed of materials no longer in use,,
is very inferior to the tooth-powders of the present day ; the best
of which are those made either of simple precipitated chalk : of
precipitated chalk with one eighth part of orris-root; or of pre-
cipitated chalk with one eighth part of camphor. Camphor has
of late been accused of doing injury to the teeth, by rendering
them brittle ; whether such be really the case I am unable to de-
cide. EDITOR.

284 MEANS WHICH PROLONG LIFE.

the digestion and assimilation of your nourishment. It
will be best to stand, or to walk about slowly. The
properest time for exercise is before meals, or three
hours after.

5th. Never eat so much that you feel you have a
stomach. It will be best to give over before you are
completely sated. The quantity of food must be always
proportioned to one's bodily labor : the less the labor,
the less ought to be the nourishment.

6th. In the choice of food one should incline more to
vegetables. Flesh has always a greater tendency to
putrefaction ; and vegetables, on the other hand, to aci-
dity, which corrects putrefaction, our continual and great-
est enemy. Besides, animal food is always of a more
heating and stimulating nature ; whereas vegetables pro-
duce cool, mild blood ; lessen the internal motion, men-
tal as well as bodily irritability ; and powerfully retard
vital consumption. Lastly, animal food yields more
blood and nourishment ; and requires, in order to be
beneficial to us, much more labor and bodily motion ;
and, by the use of it, one also is liable to become ple-
thoric. On this account it is not proper for men of let-
ters, and those who sit a great deal ; as such people do
not require so strong restoration, or so much addition
of substance, but only of those fine nourishing juices
that are necessary for the spiritual functions. One,
above all, ought to avoid flesh in summer, and when
putrid fevers are prevalent. We find that it is not
those who lived on flesh, but on vegetables, pulse, fruit,
and milk, who attained to the greatest age ; Lord
Bacon mentions a man of 120, who, during his whole
life, never used any other food than milk. The Brah-

MODERATION IN FOOD. 285

mins, by their religion, are confined merely to vegeta-
bles, and, for the most part, live to the age of 100.
John Wesley, in the middle of his life, gave over the
use of flesh ; lived upon vegetables alone, and attained
the age of 88.

7th. At night, one ought to eat sparingly, and use
little or no flesh, if cold it will be best ; and to sup a
few hours before bed-time.

8th. Never neglect to use a sufficient quantity of
drink. It too often happens that people, by inatten-
tion to the calls of Nature, forget drinking altogether,
and are no longer reminded of it ; which is the grand
cause of aridity, obstructions in the lower stomach, and
a multitude of diseases to be found so frequently among
men of letters, and females, who lead a sedentary life.
But it is to be observed, that the best time for drinking
is not while one is eating, as the gastric juices are there-
by rendered too thin, and the stomach weakened, but
about an hour after meals.

The best drink is water, a liquor commonly despised,
and even considered as prejudicial. I will not hesitate,
however, to declare it to be one of the greatest means
for prolonging life. Read what is said of it by
that respectable veteran, Theden, surgeon-general, who
ascribes his long life of more than 80 years chiefly to
the daily use of seven or eight quarts (from twenty to
twenty-four pounds) of fresh water, which he drank for
upwards of forty years. Between his thirtieth and for-
tieth year he was a most miserable hypochondriac, op-
pressed with the deepest melancholy ; tormented with
a palpitation of the heart, indigestion, etc. ; and im-
agined that he could not live six months. But from the

286 MEANS WHICH PROLONG LIFE.

time that he began this water regimen, all these symp-
toms disappeared ; and in the latter half of his life, he
enjoyed better health than before, and was perfectly
free from the hypochondriac affection. One great
point, however, is, that the water must be fresh, that is,
recently drawn from a spring or running stream, and
be put into a vessel well stopped ; for all spring water,
like the mineral, contains fixed air, which renders it
.strengthening and favorable to digestion. Pure, fresh
water has the following advantages, which certainly
must inspire us with respect for it.

The element of water is the greatest and only pro-
moter of digestion, by its coldness and fixed air it is
an excellent strengthener and reviver of the stomach
and nerves. On account of its abundance of fixed air,
and the saline particles it contains, it is a powerful pre-
ventative of bile and putrefaction. It assists all the
secretions of the body. Without water there could be
no excretion ; as, according to the latest experiments,
oxygen is a component part of it, by drinking water we
actually imbibe a new stimulus of life.

I cannot here omit to say something in favor of
soups, (liquid nourishment,) since it has been lately
fashionable to decry them as prejudicial.

The moderate use of soups is certainly not hurtful ;
and it is singular that people should imagine that it
tends too much to relax the stomach. Does not all our
drink, even though cold, become in a few minutes a
kind of warm soup in the stomach ; and does not the
stomach retain the same temperature during the whole
day ? Be careful only not to use it hot, in too great
quantity at one time, or too watery. It is attended

MODERATION IN FOOD. 287

even with great advantages. It supplies the place of
drink, particularly to men of letters, women, and all
those who do not drink, or drink very little except at
table, and who, when they give over soup, receive into
their blood too little moisture. And it is here to be
remarked, that fluids used in % the form of soup unite
much better and sooner with our juices than when
drunk cold and raw. On this account soup is a great
preventative of dryness and rigidity in the body, and
therefore the best nourishment for old people, and those
who are of an arid temperament. It even supplies
the place of medicine. After catching cold, in ner-
vous headaches, colics, and different kinds of cramp
in the stomach, warm soup is of excellent service. It
may serve as a proof of the utility, or at least ham-
lessness, of soup, when I remark that our forefathers,
who certainly had more strength than we have, used
soup ; that it is used by rustics, who are stronger than
those in refined life ; and that all the old people with
whom I ever was acquainted were great friends to it.
Wine rejoices the heart of man, but it is by no means
necessary for long life, since those who never drank
it seem to have become oldest. Nay, as a stimulant,
which accelerates vital consumption, it may tend very
much to shorten life, when used too frequently, or in
too great abundance. To render it friendly and not
prejudicial to life, it must be drunk daily, but always
in moderation : the younger a man is in less, and the
older in the greater quantity. It is best when one
considers and uses wine as the seasoning of life, and
reserves it for days of mirth and recreation to enliven
the friendly circle.

CHAPTER XIII.

Mental tranquillity. Contentment. Dispositions of mind, and
employments which tend to prolong life.

PEACE of mind, cheerfulness, and contentment, are
the foundation of all happiness, all health, and long
life. Some may here say, these are means which we
have not in our power ; they depend upon external
circumstances. But to me it appears that the case is
not so : for, otherwise, the great and rich would be the
most contented and happy, and the poor the most
miserable. Experience, however, shows the contrary ;
and more contentment, without doubt, is to be found
amidst poverty, than among the class of the rich and
wealthy.

There are sources then of contentment and happiness
which lie in ourselves, and which we ought carefully to
search out and to use. Let me here be permitted to
mention a few of these helps, recommended by the
simplest philosophy, and which I offer merely as rules
of regimen, the good advice of a physician how to pro-
long life.

1st. Endeavor above all things to subdue your pas-
sions. A man who is continually subject to the im-
pulse of his passions, is always in an extreme and ex-
alted state, and can never attain that peaceful frame so
necessary for the support of life. His internal vital

MENTAL TRANQUILLITY. 289

consumption is thereby dreadfully increased, and he
must soon be destroyed.

2nd. People should accustom themselves to consider
life not as an object, but the means of attaining to
higher perfection : and our existence and fate as always
directed to a higher aim, and subjected to a more ex-
alted power. They should never lose sight of that
point of view which the ancients named trust in provi-
dence. They will thus have the best clue to direct
their way through the labyrinth of life, and the great-
est security against all attacks by which their peace of
mind might be disturbed.

3rd. Live always, but in the proper sense, for the
day ; that is, employ every day as if it were your last,
without taking any thought for to-morrow. Unhappy
men who still think of what is to come, and, amidst
your plans and projects for the future, lose the enjoy-
ment of the present ! The present is the parent of the
future ; and he who fully employs each day and each
hour according to its destination, can in the evening lie
down to repose with the agreeable satisfaction of hav-
ing not only lived that day and fulfilled its object, but
of having also laid the best foundation for the enjoy-
ment of the future.

4th. Endeavor to form as just conceptions as possible
of every event, and you will find that the greater part
of the evils in the world arise from mistakes, false in-
terest, or precipitation; and that the principal point
is not so much what is done to us, as how we take it.
He who possesses this happy talent is independent of
external circumstances. As Weishaupt has said, " It is
certain that wisdom alone is the source of pleasure,
19

290 MEANS WHICH PROLONG LIFE.

and that folly is the source of misery. Without a total
resignation in the will of providence, a conviction that
all events are ordered for x>ur good, and that content-
ment with the world which thence arises, every thing
is folly, and will lead to dissatisfaction."

5th. One should always strengthen and confirm more
and more one's trust and confidence in mankind, and in
all the noble virtues, benevolence, friendship, affection,
and humanity which thence arise. Consider every
man as good, till you are convinced of the contrary
by incontestable proofs ; and even then man ought to
be looked upon as a being misled by error, who de-
serves our compassion much rather than our hatred.
Man indeed would be good, were he not seduced by
ignorance, misconception, and false interest. "Woe to
those whose philosophy consists in trusting no one !
Their life is a continual state of defensive and offensive
war ; and they must bid farewell to cheerfulness and
contentment. The more a man entertains good wishes
to all around him, the more will he render others
happy, and the more happiness will he himself enjoy.

6th. To promote contentment and peace of mind,
Hope is indispensably necessary. He who can hope
prolongs his existence, not merely in idea, but physi-
cally, by the peace and equanimity which he thus
secures. I do not allude here to hope within the
narrow boundaries of our present existence, but to
hope beyond the grave ! In my opinion, hope in im-
mortality is the only hope that can make life of any
value, and render the burdens of it easy and support-
able. Hope and Faith, ye great and divine virtues !
who, without you, is able to wander through a life so

CONTENTMENT AND JOY. 291

full of error and deceit, whose beginning, as well as
end, is involved in thick darkness ; the duration of
which is a moment, and in which we scarcely begin to
look forwards to futurity when we are swallowed up
by destruction. Ye are the only supports of the waver-
ing ; the greatest revivers of the weary traveller.
Those who do not honor you as exalted virtues, must em-
brace you as indispensable assistants in this terrestrial
life, and endeavor to be strong in you through a love
for themselves, if not through a love for the things that
are invisible. In this respect one can say that re-
ligion itself may be a means for prolonging life. The
more it subdues the passions, promotes self-denial, pro-
duces internal tranquillity, and enlivens the above con-
soling truths, the more will it serve to extend the
period of mortal existence.

Joy, also, is one of the greatest panaceas of life.
One must not, however, believe that it is always ne-
cessary to excite it by sought-for events and fortunate
incidents. By that frame of mind which I have al-
ready delineated, people may be rendered susceptible
of it ; and those who have attained to that happy dis-
position will never want opportunities of rejoicing.
But one should never neglect to seek and employ
every occasion of indulging in joy that is pure aifd not
too violent. No joy is more healthful, or better calcu-
lated to prolong life, than that which is to be found in
domestic happiness, in the company of cheerful and
good men, and in contemplating with delight the beau-
ties of Nature. A day spent in the country, under
a serene sky, amidst a circle of agreeable friends, is
certainly a more positive means of prolonging life than

292 MEANS WHICH PROLONG LIFE.

all the vital elixirs in the world. Laughter, that ex-
ternal expression of joy, must not here be omitted,
It is the most salutary of all the bodily movements ;
for it agitates both the body and the soul at the same
time ; promotes digestion, circulation, and respiration ;
and enlivens the vital power in every organ.

The higher pursuits and employment of the mind
deserve here a place also ; but I must remark, that it \
will be necessary to observe those prudential rules,
which I have already laid down, to prevent an abuse
of them. These higher enjoyments and pleasures are
entirely peculiar to man, and an important source of
vital restoration. Among these I reckon, above all,
the reading of agreeable and instructive books; the
study of interesting sciences ; contemplating Nature,
and examining her secrets ; the discovering of new
truths, by the combination of ideas, improving con-
versation, etc.

CHAPTER XIV.

Reality of character.

IT is well known how extremely prejudicial to life is
that occupation which renders it necessary for a man to
exist some hours daily in an assumed state, not natural
to him, I mean the employment of a player.

What then must the case be with those people who
always carry on a like occupation, who are continually
acting this or the other feigned part on the grand thea-
tre of the world, and who never really are what they
appear to be? Those indeed who are deceitful, live
always under disguise, restraint, and a false character.
They may be found, above all, among the over refined
and too highly cultivated classes of mankind : but I am
acquainted with no condition more unnatural.

It is bad enough to be obliged to wear clothes not
made for us, which everywhere pinch and confine us,
and which render every movement painful. But what
is this to wearing a false character; to a moral
restraint, where our words, conduct, gestures, and ac-
tions, are in continual opposition to our internal feel-
ings and wishes ; where we violently suppress our
strongest natural propensities, and assume foreign ones ;
and where we are obliged to keep continually strained,
every nerve and every vessel, in order to carry on that
deception which is our whole existence ? Such a false

294 MEANS WHICH PROLONG LIFE.

state is nothing else than a continual cramp ; and this
is proved by the consequences. An incessant restless-
ness and anxiety, deranged circulation and digestion,
continued contradiction both physical and moral, are
its unavoidable effects. In the end, it becomes impossi-
ble for these unfortunate men to lay aside this assumed
character ; so that it becomes a second nature. They
are at length lost, and cannot again find themselves.
In a word, this false state keeps up continually a secret
nervous fever. Internal irritation, and external cramp,
are, both, parts of it ; and it must lead to destruction
and the grave, the only place where such wretched be-
ings can hope ever to lay aside the mask.

CHAPTER XV.

Agreeable stimulants of the senses and of sensation
moderately used.

THESE have a double effect in the prolongation of
life. In the first place, by their immediate influence
on the vital power, they enliven, strengthen, and exalt
it ; and, secondly, by increasing the activity of the
whole machine, they put into much greater activity the
organs of digestion, circulation, and secretion, which
perform the most important functions of restoration.
A certain cultivation and refinement of our sensibility
is therefore healthful and necessary ; because it renders
us more susceptible of these enjoyments ; only it must
not be carried too far, else it may become a disease.
In stimulating the senses also great care must be taken
not to exceed the proper measure ; for the same enjoy-
ment which, when used in a moderate degree, is capa-
ble of restoring, may, if used too much, consume and
exhaust.

All agreeable stimulants, which can affect us through
the sight, hearing, smell, taste, and feeling, may be in-
cluded under this head ; and therefore the pleasures of
music, painting, and the other imitative arts, poetry,
etc., as they can exalt and renew these enjoyments.
In the present view, however, it appears to me that
Music deserves the preference, because no mental im-

296 MEANS WHICH PROLONG LIFE.

pression can have so speedy and immediate an effect in
tuning, enlivening, and regulating the vital operations.
Our whole frame assumes spontaneously the tone and
character of the music; the pulse becomes either
quicker, or more calm ; the passions are roused, or soft-
ened, according to the will of this language of the soul,
which, without words, merely through the power of
melody and harmony, acts immediately upon our most
internal organs, and by these means enchants us often
more irresistibly than eloquence itself. It is much to
be wished that the study of music in this view were
more common, and that it were more employed for
such a noble purpose.

CHAPTER XVI.

Preventing diseases. Judicious treatment of them. Proper use of
medicine and physicians.

DISEASES, as has been already shown, belong for
the most part, to those causes which shorten life, and
are even capable of breaking the vital thread abruptly.
The business of medicine is to guard against these, as
well as to cure them : and so far medicine may be
considered and employed as a mean for prolonging life.

But error, here, is too common. Sometimes it is be-
lieved that this beneficial art can never be sufficiently
employed, and that people can never take too many
medicines. Sometimes it is so much abhorred, as some-
thing unnatural, that too few are used ; and sometimes
the falsest conceptions are formed of medicine, as well
as of physicians ; and both are employed in an impro-
per manner. To this may be added, in modern times,
a multitude of popular books, by which a great deal of
crude, undigested information on medical subjects has
been diffused among the public ; and hence a greater
misapplication of medicine has been occasioned, and the
utmost injury to the health of mankind in general.

It is impossible for every one to be a physician.
Physic is a science so extensive and difficult, that it re-
quires close and long-continued study, and even a pecu-
liar formation of mind and of the higher powers of the

298 MEANS WHICH PROLONG LIFE.

soul. An acquaintance with the rules and means for
curing diseases does not form a physician, as some im-
agine. These rules and means are the result of medi-
cal experience ; and he only who can perceive the con-
nection of them with the causes of disease, and the
whole chain of grounds and inferences from which they
are deduced, in a word, who can himself discover these
means, deserves to be called a physician. From this
it appears that the art of medicine never can be known
by the generality of the public.

That branch of the medical art only which teaches
an acquaintance with the human body, so far as it
may be useful for every man to know, and the method
and manner of guarding against diseases and preserv-
ing health, both individually and generally, can, or
ought to, form a part of that instruction and informa-
tion which should be communicated to the public.
This is evident from the simple idea of disease, and the
helps to be applied. What is meant by administering
medicines and curing diseases ? Nothing else than by
an unusual impression to produce an unusual change
in the human body, by which an unnatural state named
disease may be removed. Disease and the operation
of medicines are each an unnatural state ; and the ap-
plication of medicine is nothing else than exciting an
artificial disease, in order to expel one that is natu-
ral. This may be seen when a man in good health
takes physic, which will always render him ill in a
greater or less degree. The use of medicine is, there-
fore, of itself prejudicial ; and can be excused and ren-
dered healthful only when a more diseased state of the
body is thereby removed. This right of making one's

JUDICIOUS APPLICATION OF MEDICINE. 299

self or others sick artificially, ought never to be exer-
cised but by those who are sufficiently able to discover
what proportion the disease may bear to the means ;
consequently, by physicians ; otherwise it may happen
that, when the means perhaps are altogether unneces-
sary, one may be rendered ill ; or that the means will
not be suited to the disease, and therefore the poor
patient must suffer under two maladies instead of hav-
ing one ; or that the means may promote and increase
the diseased state already existing. In cases of disease
it will be far better to use no medicine at all, than to
employ that which is not proper.

As none, therefore, but people regularly bred, ought
to be allowed to practise medicine, this important ques-
tion arises : How must medicine be used when we wish
to employ it as the means of prolonging life ? In order
to answer the above question, I shall here give some
general rules and definitions.

But, first, let me be permitted to say a few words on
a part of this research, which, though most interesting
to the physician, is of too much importance even to
others to be passed over in silence. I mean, How does
the practice of physic, in general, contribute to the pro-
longation of life ? Can one consider it absolutely as a
means for prolonging our existence ? Without doubt
we can, so far as it cures disorders that might destroy
us, but not always in other respects: and I shall
here add, for the consideration of my medical brethren,
a few observations which may show that to restore
health and prolong life are not the same ; and that the
point is not merely to cure a disease, but how it is cured.
First, it is certain, from what has been said, that medi-

300 MEANS WHICH PROLONG LIFE.

cine operates by occasioning an artificial illness. Every
disease is attended with irritation and a loss of power*
If the medicine, therefore, be more powerful than the
disease, the patient will be cured ; but he will be more
weakened by the process of the cure, and more will be
deducted from the duration of his life than would have
been taken from it by the disease. This is the case
when people, on trifling occasions, employ immediately
the most powerful. and the most violent medicines. Se-
condly, a disease may be cured by various ways and
methods. The difference is, that one leads the crisis
sometimes to one part, and sometimes to another ; or
that the disorder is removed sooner by one method, and
more slowly by another. These different modes of
cure may all, however, lead to a restoration of health,
but be of very different effect in regard to the prolon-
gation of life. The more a cure allows the disease to
continue, and to weaken the powers and the organs ;
or the more it affects the organs necessary for life, or
conducts the disease thither, and consequently impedes
afterwards vital restoration (as for example, when the
important system of digestion is made the seat of the
disease, and weakened by powerful remedies) ; or lastly,
the more a cure wastes unnecessarily the vital power in
general, as by too profusely bleeding, withdrawing
the usual nourishment too incessantly, etc., the more
will it weaken the grounds of longevity, even though it
may remove the disease. Thirdly, one must never for-
get that disease itself may be useful and necessary for
prolonging life. There are many diseases which are
nothing else than an exertion of Nature to restore equili-
brium that has been destroyed, to evacuate corrupted

PREVENTION OF DISEASES. 301

matter, or to dissipate obstructions. If a physician,
therefore, (according to the true Brownonian method,)
does nothing more than check the disease from showing
itself outwardly, without paying attention to remote
causes and consequences, he only destroys the active
counteraction of Nature, by which it endeavors to re-
move the real disease : he quenches the fire outwardly,
but suffers it to burn more violently within. He nour-
ishes the germ, the material cause of the evil, which
perhaps would have been banished by this process of
Nature had it been suffered to be completed, and ren-
ders it stronger and more incurable. We have too
many instances of patients who believed themselves
perfectly cured of a fever or the dysentery, and who
afterwards became hectic, or fell into the hypochon-
driasis, nervous weakness and the like. No one will
deny that such a cure, though it seems for the present
to restore the patient to health, may nevertheless
shorten the duration of his life.

I shall now proceed to answer a question which con-
cerns those only who are not physicians : By what means
can diseases be prevented; how ought those which have
already appeared to be treated; and, in particular, how
ought physicians and the medical art to be employed in'
order to contribute in the highest degree possible to the
support and prolongation of 'life ?

But let me first speak of the means to be used for
preventing diseases. As there are two things which
belong to the origin of every disease, the cause that
excites it, and the capacity of the body for being
affected by this cause, there are two ways by which
disease may be prevented, either to remove that cause,

302 MEANS WHICH PROLONG LIFE.

or to destroy the sensibility of the body in regard to it ;
and upon this is founded the whole medical dietetic, and
all the preventative methods. The first method which
has been most commonly pursued, is the most uncer-
tain ; for, as long as we are not able to alter our mode
of living, it will be impossible to guard against every
cause of disease; and the more we deviate from it,
the more we shall be affected by them when they
attack us. For instance, cold never hurts any one so
much as those who, in general, keep themselves ex-
ceedingly warm. Far better is the second method,
to endeavor to guard against hose causes of disease
which can be avoided; and to accustom one's self to
the rest, in order that the body may be rendered insen-
sible to them.

The principal causes of disease, which can, -in a great
measure, be guarded against, are, intemperance in eat-
ing and drinking, immoderate enjoyment of physical
love, great heat and cold, or a sudden transition from
the one to the other; passions, violent exertion of
the mind, too much or too little sleep, checked evacua-
tions, and poisons.

One ought, however, to render the body less sus-
ceptible of these causes, or to harden it pathologically ;
and for that purpose I recommend the following
means : First, the daily enjoyment of free air. In
good or bad weather, during rain, wind or snow, the
excellent practice of walking or riding for a few hours
in the open air, must be continued every day without
exception. This will contribute in an incredible degree
to harden the constitution, and to promote longevity;
and, when done daily, the body will soon become so

PREVENTION OF DISEASES. 303

strong as to be affected by no kind of weather. It is
to be recommended, therefore, in particular, to those
who are subject to the gout and the rheumatism.
Secondly, to wash daily the whole body with cold
water ; not to keep one's self too warm ; and to pre-
serve the activity of the body. Never let the body
sink into too passive a state, but endeavor, by muscular
motion, friction, and gymnastic exercises, to keep up in
it a kind of counteraction. The more passive the
body is, the more susceptible will it be of disease.
Lastly, a certain freedom and immunity from restraint
in your way of life ; that is to say, do not bind your-
self too rigidly to certain rules and habits, but allow
yourself a moderate indulgence. Those who confine
themselves with too much severity to order and r ^gi-
men, be they ever so good, make themselves thereby
more susceptible of disease ; for if they deviate in the
least from what is now become to them a second nature,
some kind of indisposition will be the consequence. A
little irregularity, by the gentle revolutions which it
effects in the body, may be of great use in purifying,
opening, and dissipating; and even pernicious things
lose a great deal of their noxious quality when one is
accustomed to them. A little less sleep than usual ;
to drink sometimes a glass more than common; to
eat a little more food, or substances harder of digestion ;
to expose oneself to cold or heat by riding, dancing,
and the like ; to take exercise till one is tired, and
sometimes to fast a day, are all means, therefore, that
contribute to harden the body, and which give more
latitude to the health, as they free it from too slavish a

304 MEANS WHICH PROLONG LIFE.

dependence on the uniformity of habit, to which it is
not always possible for us to be confined.

A grand point in guarding against disease is, that
every one should try to discover to what malady he
is constitutionally most disposed, in order that this
tendency may be destroyed, or at least that all oppor-
tunity of its being converted into disease may be re-
moved. On this is grounded individual regimen ; and
every man ought to observe that which is proper for
him, so far as to counteract his particular morbific dis-
position. To inquire into and determine this point is
indeed the business principally of the medical practi-
tioner ; and I am therefore of opinion, that people, on
a subject of so much moment, should consult an intelli-
gent physician, and allow him to judge what diseases
they have the greatest disposition to, and what regi-
men may be best suited for them. In this respect the
ancients were more prudent than we. They employed
the medical art and physicians chiefly for determining
their dietetic mode of life ; and even their astrological,
chi romantic, and other researches of the like kind,
tended, at bottom, to define the moral and physical
character of man, and to prescribe for him accordingly
a proper mode of living and regimen. They undoubt-
edly did much better in thus employing their physi-
cians than if they had run to them every week to make
them prescribe for them purgatives or emetics. But
for this purpose a judicious, prudent, and acute physi-
cian is necessary ; while, on the other hand, any em*
piric is capable of writing a prescription. These people,
at any rate, had a surer means of distinguishing a false
from a true prophet.

KNOWLEDGE OP THE CONSTITUTION. 305

That those unacquainted with the medical art may
be enabled, as much as possible, to determine the na-
ture of their constitution, and what tendency it has to
disease, I shall here give the following rules :

1st. Examine what disposition to disease you inherit
from your parents. There are certain morbific ten-
dencies which may be communicated by generation,
such as to the gout, indigestion, nervous weakness, and
consumption. If these evils have taken root in the
parents, there is great reason to suspect a disposition
to them in the children. By a proper regimen they
can, however, be prevented from attaining to a great
height.

2nd. A disposition to some disorders may be created
by the first treatment in infancy ; especially if a child
be kept too warm, which excites a tendency to perspi-
ration, renders the skin flaccid, and, by these means,
disposes the body to rheumatic disorders. Too early
application to learning, gives a tendency to nervous
weakness, and diseases of the nerves.

3rd. A tendency to certain diseases is connected
with some forms and kinds of bodily structure. Those
who are tall and thin, who have a long slender neck y
a flat breast, projecting shoulders, and who have grown-
up suddenly to a great height, must be on their guard
chiefly against consumptions, and in particular as long
as they are under the age of thirty. Those who have
a short thickset body, a large thick head, with a short
neck, so that the head seems to be stuck between the
shoulders, show a disposition to apoplexy; and must
beware of every thing that may give occasion to that
disease. In general, all overgrown people have a ten-
20

306 MEANS WHICH PROLONG LIFE.

deney more or less to consumption and disorders of the
breast.

4th. Every man ought carefully to examine his tem-
perament. If it be sanguine or choleric, it gives a
tendency to inflammation ; but if phlegmatic or melan-
cholic, to chronic diseases and weakness of the nerves.

5th. The climate also, and the spot in which one
lives, may create a tendency to disease. If they are
cold and damp, one may rest assured that they will
produce a disposition to nervous and bilious fevers,
ague, gout, and rheumatism.

6th. To pay attention, in particular, to one's weakest
part is of importance. Every man, in a physical sense,
has his weak side ; and all causes of disease are ac-
customed, in general, to fix themselves in those parts
which are by nature weakest. Those, for example,
who have weak lungs, will be affected chiefly in that
part ; and every thing almost will give rise to a catarrh
or disorder of the chest. If the stomach be weak, it
will be acted upon by every slight cause ; and indiges-
tion, crudity, and foulness of it will be the consequence.
If one is acquainted with these parts, one may contrib-
ute very much to the prevention of disease, and the
prolongation of life ; partly by guarding them against
morbific causes, and partly by strengthening them, and
depriving them of their too great sensibility. As much
depends, therefore, on acquiring the art how to dis-
cover the weakest parts of one's body, I shall give the
following signs, which may be understood by those
even who are not physicians : Observe on what
parts any mental shock, or violent affection, produces
the greatest effect; for these are the weakest. If

USES OF THE MEDICAL ART. 307

these causes immediately excite a cough or uneasy
sensation in the chest, the lungs are the part pointed
out ; if they occasion a compression of the stomach,
flatulency, and the like, one may be assured that the
weak part is the stomach. Observe also where the
effects of other morbific influences are reflected; as,
for example, the effects of a surfeit, a cold, overheating,
violent exercise, etc. If the chest be attacked, that
may be considered as the weakest part. It is of equal
importance to observe which way the blood and juices
have the greatest tendency ; what parts are usually the
reddest and the hottest, and where perspiration appears
in the greatest abundance ; for, there, if the rest of the
body do not perspire, will disease most readily fix itself.
One may also, in general, conclude that any part wnich
one uses violently and immoderately, or which one
overstrains, will become weaker : for example, the
brain among studious people ; the chest among singers ;
the stomach among gluttons, etc.

I shall now proceed to answer the question, In what
manner should a disease which has already taken place
be treated, and ivhat use ought to be made of physicians
and of the medical art ? The most important part of
the answer may be reduced to the following rules :

1st. Never use medicine without a sufficient cause ;
for, who wish to make themselves sick unnecessarily ?
The custom, therefore, of purging, bleeding, and the
like, at stated periods, merely for the purpose of guard-
ing against a possible evil, is highly prejudicial. This
practice often gives rise to those disorders which one
endeavors to avoid.

2d. It is much better to prevent diseases than to cure

308 MEANS WHICH PROLONG LIFE.

them ; for the latter is always connected with a greater
loss of the powers, and consequently of vital duration.
Let the above means, therefore, for guarding against
them be carefully observed.

3d. As soon, however, as disease makes its appear-
ance, the greatest attention ought to be paid to it ; for
the most trifling indisposition may conceal under it a
very serious malady. This is the case, in particular,
with feverish disorders. The commencement of them
is shown by the following symptoms : One experi-
ences an uncommon lassitude ; the appetite fails, and
one has a much greater desire for drinking ; the sleep
is interrupted or disturbed by dreams ; the usual ex-
cretions are checked, or increased in an unnatural
manner ; one has no inclination for labor, and is af-
fected by headache, and a greater or less degree of
coldness, which is followed by heat.

4th. As soon as one perceives these symptoms,
nothing is so necessary as to lessen one's nourishment,
which strengthens the disease, and to follow the benefi-
cent instinct of Nature, which every animal, to its great
advantage, obeys on such occasions. Let the patient
abstain from eating ; for Nature, by rejecting food,
shows that she is incapable of digesting it ; and let him
drink a little more than usual, but only water, or some
other light beverage. One ought also to be kept
quiet ; to lie in the best position, for the lassitude suffi-
ciently shows that Nature requires her strength for
modifying the disease ; and one ought to avoid both
heat and cold, consequently should neither go out into
the open air, nor be shut up in a warm apartment.
These simple means, prescribed to us so clearly by

QUALITIES OF A PHYSICIAN. 309

Nature herself, are capable, would we only listen to
her voice, of checking an infinite number of diseases in
their very birth. Old Macklin, that veteran of the
London stage, who died in his 99th year, used to say,
that, when he found himself ill, during the long course
of his life, he always went to bed took nothing but
bread and water and that by this regimen he was
generally relieved from every slight indisposition. I
knew a respectable magistrate of fourscore, who, when
indisposed, did nothing else than fast, smoke tobacco,
and observe the above rules ; by which means he had
never occasion for medicine.

5th. If one has an opportunity of conversing with a
physician, he ought to be consulted, not so much
respecting prescriptions, as the state of one's body.
Should such an opportunity be wanting, it is much bet-
ter to prevent by the negative method an increase of
the disease, than to employ any thing positive, which
may perhaps do hurt. No medicine, indeed, ought to
be considered as a matter of indifference. Purgatives
even, if used at an improper time, may be highly pre-
judicial. If my readers be desirous of knowing the
most harmless, it is a teaspoonful of cream of tartar
stirred round in a glass of water; or the following
draught, which certainly is one of the most general
remedies for feverish disorders : Take half an ounce
of cream of tartar, and boil it with six pounds of water,
in a new earihen pot, until the powder is wholly dis-
solved. After it is taken from the fire, add to it an
orange cut into slices, with from an ounce and a half to
three ounces of sugar, according to taste, and then put
it into bottles for use. This may serve as one's com-
mon beverage.

310 MEANS WHICH PROLONG LIFE.

6th. Be ingenuous with your physician, and give
him a true account of your past life, so far as it may
relate to the disease ; and forget no unfavorable cir-
cumstance, especially when the case is stated in writ-
ing. Avoid, in particular, all reasoning on it, which is
a common fault, or of giving any representation accord-
ing to a preconceived opinion, but relate merely what
you have observed in as unprejudiced a manner as
possible.

7th. Make choice of a physician in whom you can
place confidence, but none of those who deal in arcana,
who are too talkative or inquisitive, who value them-
selves above others, or who endeavor to make the con-
duct of others appear in a dubious light; for this
always betrays ignorance, a bad head, or a bad heart ;
in short, none of those who are fond of prescribing
strong powerful medicines, or who, according to the
common saying, will either cure or kill.

8th. Avoid in particular a physician whose princi-
pal object in his practice is avarice or ambition. A
real physician ought to have no objects but the health
and preservation of his patients ; any others mislead
him from the true path, and may be attended with the
most prejudicial consequences to those who employ
him. If he happen to be so situated with a case, that
either his reputation or his pocket will suffer, if he
venture any thing for the relief of his patient, he will
certainly rather allow the patient to die than lose his
reputation. He will also be interested in the fate of
his patients, in proportion to their rank and their
riches.

9th. The best physician is he who is at the same

SELECTION OF A PHYSICIAN. 311

time a friend. One may be open-hearted with such a
man, and place confidence in him. He is acquainted
with his patients, and observes them when in a state of
health, which is of the utmost importance to enable him
to treat them in a proper manner when attacked by
disease. In short, he is strongly interested in their
condition, and will exert himself with more activity and
attention to restore their health, than the physician who
acts merely in that capacity. People, therefore, ought
to do every thing in their power to unite themselves in
the tenderest bonds of friendship with their physician ;
and never to dissolve their intimacy by want of confi-
dence, peevishness, pride, or any other impropriety of
behavior, which is so often shown towards physicians,
but always with more injury to the patient.

10th. Be greatly on your gaurd against any physi-
cian who prepares and employs secret medicines ; for
he is either an interested man, who values his own
advantage far above the lives and health of his patients,
or an ignorant impostor ; and no impostor is more
destructive than he who deprives you, not only of your
money, but also of your health. If a secret be of any
value, and useful to mankind, it should be the property
of the public, and ought to be made known for the gen-
eral benefit ; and he who discloses it is entitled without
doubt to immortal honor. Those also who conceal
such remedies do injury to thousands ; because people
cannot use them properly, not being well enough
acquainted with them ; or because they cannot be pro-
cured in common, and be employed by a judicious phy-
sician.

llth. Nowhere, in general, ought one to be more

312 MEANS WHICH PROLONG LIFE.

attentive to morality of character than in the choice of
a physician ; for where is it more necessary ? If he to
whom you blindly intrust your life, who is subject to
no tribunal but that of his conscience, and who, to dis-
charge in a complete manner the duty of his calling,
must sacrifice all rest and pleasure, nay his own health
and life, if this man do not act according to the pure
principles of morality, but makes policy, as it is called,
his motive, he is a detestable and dangerous character,
and ought to be avoided with greater care than the
most destructive disease. A physician without morals
is not a nonentity he is a monster.

12th. If people, however, meet with an able and
honest physician, they ought to intrust themselves to
him with full confidence. This will tend to make the
minds of the patients quiet, and be of great service to
assist the physician in effecting a cure. Many believe,
that the more physicians they collect around them, the
more certain they must be of relief ; but this is a gross
error. I here speak from experience. One physician
is better than two two than three and so on in
proportion. In the same ratio as physicians are
increased will the probability of cure decrease ; and
in my opinion, there is a certain point of medical over-
loading, in which a cure is physically impossible.
Some cases, indeed, may occur, but very seldom, in
which a disorder, by being secret or complex, may
require a consultation of several. One, however,
ought to call in only those who are known to be
judicious men, and who will act in concert ; and to
employ such consultations for discovering and defining
the disease, and to form a plan of the method to be fol-

SELECTION OF A PHYSICIAN. 313

lowed in the cure. The application of it should always
be permitted to one, and to that practitioner in whom
people have the greatest confidence.

13th. One ought carefully to observe the crises, or
helps and means of which Nature seems to be fondest,
and which she perhaps may have employed on former
occasions, and whether she is accustomed to assist her-
self by perspiration, diarrhoea, bleeding at the nose, or
otherwise. The same means one must endeavor to
promote in every disease of the like kind ; and such
information is of great importance to the physician.

14th. To pay attention to cleanliness is a precept
indispensably necessary to be observed in regard to
every disease ; for, by means of dirt, any disorder may
be converted into one putrid, and far more dangerous.
By neglecting this point, therefore, people injure not
only their friends and relations, but also the physician,
who may thus be deprived of his own health. The
patient's linen, on this account, ought to be changed
daily, but at the same time with some caution ; the air
ought to be renewed in his apartment, and all offensive
matters should be speedily conveyed from it. As few
people as possible should bfe suffered to continue in it ;
and all animals, flowers, remains of food, old clothes,
and in short every thing that may produce evaporation,
ought to be removed from it.

CHAPTER XVII.

Relief in cases where one is exposed to the danger of sudden
death.

THERE are certain causes which, where the health is
perfectly sound, and where one has the best capacity for
long life, may suddenly interrupt and destroy the vital
operation. I here allude to the violent causes of sudden
death ; and as to lessen these, or to render them harm-
less, is an important part of the art of preserving and
prolonging life, I shall lay before my readers what in-
formation may be necessary on the subject.

To this head belong all violent kinds of death, which
may be effected either by mechanical injuries, or organic
derangement ; and they may all be reduced to three
classes. They either render the vital organs unfit for
performing their functions ; destroy suddenly the vital
power, as lightning, violent passion, and the greater part
of poisons ; or they suddenly destroy vital irritability,
without the continual agency of which there could be no
vital exertion.

The method of counteracting these is twofold. One
can either guard against them or destroy their effect
after they have already begun to act.

I shall first speak of the means by which one can
guard against them. It is impossible to keep at a dis-
tance all these causes ; for they are so connected with

RELIEF IN CASES OP VIOLENT DEATH. 315

our life, and in particular with the employment of many,
that one must resign life itself in order to avoid them.
We can, however, procure to our bodies a great degree
of immunity from them, and give it some properties by
which it will be put in such a condition as to sustain
little or no hurt from them when they approach it.
There is, therefore, an objective and a subjective art of
guarding against the dangers of death ; and the latter is
that in which every one should endeavor to acquire a
certain degree of perfection. In my opinion, it is neces-
sary for the formation and education of man. The
means are exceedingly simple.

1st. Endeavor to give to the body the utmost possible
agility and readiness in all bodily exercises. A suffi-
cient cultivation of the corporeal powers, by running,
climbing, tumbling, swimming, walking on any narrow
ridge, etc. will be a great means of securing one from
dangerous accidents ; and were such a part of education
more common, fewer people would lose their lives by
drowning, falls, and other misfortunes of the like kind.

2d. The judgment should be formed, and one's
knowledge rectified, by the study of natural philosophy,
and natural history, in regard to every pernicious pow-
er. To this belongs an acquaintance with the nature of
poisons ; the properties of lightning, and the means of
avoiding it ; the noxious quality and effects of mephitic
air, frost, etc. To give sufficient cautions on this sub-
ject, it would be necessary for me to write a whole
treatise ; and I sincerely wish that some one would
undertake such a work, and that it may be introduced
into schools.

3d. Endeavor to render the mind intrepid ; to give it

316 MEANS WHICH PROLONG LIFE.

strength and philosophical equanimity ; and accustom it
to sudden and unexpected events. This will be doubly
beneficial. One will thereby guard against the physical
injury of sudden and alarming impressions, and will
have more presence of mind to pursue the means proper
to be used in cases of sudden danger.

4th. Give to the body a sufficient degree of harden-
ing against cold and heat, or any changes of the like
kind. Those who possess this property will be able to
brave death on many occasions, when others will be
obliged to submit to it.

But, in regard to the danger of death actually existing :
What is to be done in cases of drowning, hanging, suffo-
cation, poisoning, or being struck with lightning, etc. ?
Even here there are means by which persons appar-
ently dead have been happily brought again to life ;
and this is a part of medicine which every man should
understand, for such accidents may occur to every one,
and every thing depends on assistance being given
speedily. In cases of so much danger, each moment is
precious ; and the simplest means employed imme-
diately, may effect more than the whole wisdom of an
JEsculapius could half an hour later. He who first
arrives when an accident has taken place should con-
sider it as his duty to apply help instantaneously, and
carefully reflect that the life of an unfortunate being
may depend on a minute sooner or later.

The violent kinds of death, in regard to their treat-
ment, may be divided into three classes.

The first class comprehends suffocation by hanging,
drowning, or foul air, and death, or the being struck by
lightning, with the mode of treatment. The first and

BELIEF IN CASES OF VIOLENT DEATH. 317

most effectual means in such cases are the follow-
ing :

1st. Be as expeditious as you can to draw the body
from the water, or to cut the rope, in a word, to remove
the cause of death. This alone is sufficient to save the
unfortunate person, if it be done speedily ; but attention
to that point is too much neglected. In most places,
apparatus is kept for giving relief in such cases ; but
people in general are so slow in applying it, that one
might believe it intended rather for the funeral cere-
mony, than for saving the life of a fellow-creature. I
am, therefore, fully convinced, that better machinery
for dragging up the bodies of drowned persons would
be far more valuable than all the apparatus for restoring
suspended animation; and when one sees how unwil-
lingly and in how awkward a manner people undertake
this business, how averse they are to it, and what pre-
judice prevails against it, one will not wonder that so
few unfortunate persons should be saved in Germany.
I must therefore entreat all governments to endeavor
to bring this part of the establishment for restoring life
to greater perfection ; and here I include rooting out
prejudice,* disputes respecting jurisdiction, the payment
of the reward, and the punishment of voluntary delay.

2d. The body should be immediately stripped, and

* Of this kind is the shameful dread of the dishonor and dis-
grace which attend the touching of such unfortunate people ; tho
diabolical superstition of many fishermen, that one must not draw
the body of a drowned person from the water before sunset, in
order that the fish may not be frightened away ; or that some
rivers must have an annual offering ; and other ideas of the like
kind, which prevail among the vulgar much more than one might
imagine.

318 MEANS WHICH PROLONG LIFE.

every endeavor should be made, as speedily as possible,
to excite in it a general warmth. Heat is the first and
most general stimulus of life. The same means which
Nature employs to quicken life in the beginning, are
also the most powerful to produce life a second time.
The best thing for that purpose is the tepid bath ; but
if this cannot be had, the patient may be covered with
warm sand, ashes, or thick blankets in a bed ; and hot
stones should be applied to various parts of the body.
Without these means, all others will be of little avail ;
and it is much better to warm thoroughly persons ap-
parently dead, than to use cupping, friction, or the like,
and at the same time to suffer them to become stiff with
cold.

3d. To convey air into the lungs is the next process
in point of importance, and may be connected with the
excitation of heat. It is, indeed, most beneficial when
it is done with oxygen gas by means of a pipe and a
pair of bellows. But in urgent cases, and to save pre-
cious time, it will be sufficient if one presses on the chest
so as to expel the air which it contains, and then, by
withdrawing the pressure, allows it to expand by its
own elasticity, and thus fill the lungs with air. This
should be done with regularity, so as to imitate ordinary
breathing.

4th. Let fall now and then, from a certain height,
drops of frigid water or wine on the pit of the stomach.
This sometimes has given the first stimulus to restore
the motion of the heart.

5th. Rub with a cloth or flesh-brush the hands and
soles of the feet, the belly and the back : irritate the
sensible parts of the body, such as the soles of the feet

SUSPENDED ANIMATION. 319

and hollow of the hands, by friction with stimulating
oils ; the nose and throat, by means of a feather, or by
holding to the nostrils, and dropping on the tongue,
volatile spirit of ammonia, etc.

6th. Ad soon as signs of life begin to appear, pour a
spoonful of good wine into the mouth ; and when the
patient swallows it, repeat the same thing often. In
cases of necessity brandy may be used, but mixed with
two-thirds of water.

7th. For those who have been struck by lightning,
the earth bath is to be recommended. The body may
be either laid, with the mouth open, against a spot of
earth newly dug up, or fresh earth may be scraped
round it up to the neck.

If these simple means, which every one can anl
ought to use in regard to his fellow-citizens, when ex-
posed to the danger of sudden death, be speedily em-
ployed, they will be of more service than the most com-
plete apparatus applied half an hour later ; and at any
rate the intermediate time will not be entirely lost, and
the feeble vital spark may be prevented from being
totally extinguished.

In the second class is comprehended those who have
been frozen. These require a mode of treatment
entirely different ; for by warmth they would be des-
troyed altogether. Nothing further is to be done than
to immerse them in snow up to the head ; or to place
them in a bath of the coldest water that can be pro-
cured without being frozen. Here life will return of
itself; and as soon as any signs of it appear, give the
patients a little warm tea with wine, and put them to
bed.

320 MEANS WHICH PROLONG LIFE.

The third class contains those who have been poi-
soned. It is here to be observed, that we are in pos-
session of two invaluable remedies, proper for any
poison, which may be everywhere found, and which
require no previous acquaintance with medicine I
mean milk and oil. By the help of these only, the most
dreadful of all the kinds of poisoning, that by arsenic,
has been cured. Both of them answer the principal
object, which is to expel the poison, or to destroy its
power. Let persons therefore, who have been poi-
soned, drink as much milk as they can (if it in part
comes up again, so much the better) ; and let them,
every quarter of an hour, take a cupful of oil of any
sort ; for it is all the same whether it be oil of linseed,
almonds, poppies, or common oil. If it be known with
certainty that the poison is arsenic, corrosive sublimate,
or any other metallic salt, dissolve soap in water, and
let the patient swallow it. This will be sufficient till a
physician arrive, and will often render his assistance
unnecessary.

CHAPTER XVIII.

Old age. Proper treatment of it.

OLD age, though the natural consequence of living,,
and the commencement of death, can itself, on the
other hand, be a means for prolonging our existence.
It does not, however, increase the power to live, but it
retards its being exhausted ; and one may thus affirm,
that a man in the last period of life, at the time when
his powers are lessened, would, were he not old, finish
his career sooner.

This position, which appears to be somewhat para-
doxical, is confirmed by the following explanation :
Man, during the period of old age, has a much smaller
provision of vital power, and much less capacity for
restoration. If he lived with the same activity and
vigor as before, this provision would be much sooner
exh^isted, and death would soon be the consequence.
Now the character of age lessens the natural irritability
and sensibility of the body, by which the effects of in-
ternal as well as external irritation, and consequently
the exertion and wasting of the powers, are also les-
sened ; and, on this account, as consumption is less, he
can with such a stock of powers hold out much longer.
The decrease of the intensity of the vital processes, as
age increases, prolongs therefore vital duration.

Irritability being thus lessened, lessens also the effect
21

322 MEANS WHICH PROLONG LIFE.

of pernicious impressions and morbid causes, such as
the passions, overheating, etc.; it preserves likewise
much greater quietness and uniformity in the internal
economy, and in that manner secures the body from
many diseases. It is observed that, for this reason
also, old people are much less attacked by infectious
disorders than those who are young.

To this may be added the habit of living, which,
without doubt, in the latter period of one's days, con-
tributes to the support of life. An animal operation,
which one has carried on so long, always in the same
order and succession, becomes at last so customary that
it continues through habit when the action of other
causes ceases. It is often astonishing how the greatest
debility of age will hold out, provided every thing
remain in its usual order and succession. The spirit-
ual man is sometimes actually dead; and yet the
vegetative, the man-plant, still continues to live; but
for the latter, indeed, much less is necessary. To this
habit of life it is owing also that a man, the older he
grows, becomes still fonder of existence.

If old age, therefore, be properly treated and sup-
ported, it can be employed, in some measure, . as a
means of prolonging life ; but as this requires devia-
tions from the general laws, I consider it necessary to
give the rules proper to be observed.

The principal points in this treatment are, that one
must always endeavor to lessen and soften the increas-
ing dryness and rigidity of the vessels, which at length
occasion a complete stoppage- of the whole machine;
that nourishment and restoration of what has been lost
must be facilitated as much as possible ; that stronger

TREATMENT OF OLD AGE. 323

irritation must be given to the body, because the natu-
ral irritability is so much weakened ; and that one must
promote excretion of the corrupted particles, which in
old age is so imperfect, and which therefore produces
an impurity of the juices, that accelerates death. Upon
these are grounded the following rules :

1st. As the natural heat of the body decreases in old
age, one must endeavor to support and increase it ex-
ternally as much as possible. Warm clothing, warm
apartments and beds, heating nourishment, and, when
it can be done, removal to a warmer climate, are all
means, therefore, that contribute greatly to the prolon-
gation of life.

2nd. The food must be easy of digestion, rather
fluid than solid ; abundant in concentrated nourish-
ment ; and at the same time much more stimulating
than would be advisable at an earlier period. Warm,
strong, and well-seasoned soups, are, therefore, bene-
ficial to old age ; and also tender roast meat, nutritive
vegetables, good nourishing beer, and, above all, oily
generous wine, free from acid, earthy and watery par-
ticles, etc., such as Tokay, Spanish, Cyprus, and Cape
wines. Wine of this kind is one of the most excellent
stimulants of life, and that best suited to old age. It
does not inflame, but nourishes and strengthens : it is
milk for old people.

3d. The tepid bath is exceedingly well calculated to
increase the natural heat, to promote excretion, partic-
ularly of the skin, and to lessen the aridity and stiffness
of the whole frame.

4th. Guard against all violent evacuations, such as
letting blood, unless when required by particular cir-

324 MEANS WHICH PROLONG LIFE.

cumstances; strong purging, exciting perspiration by
too much heat, indulging in excesses of any kind.
These exhaust the few powers still remaining, and
increase aridity.

People, with increasing years, should accustom them-
selves more and more to a certain order in all the vital
operations. Eating, drinking, motion, and rest, the
evacuations, and employment, must have their deter-
mined periods and succession. Such mechanical order
and regularity, at this season of life, may contribute
greatly to the prolongation of it.

6th. The body, however, must have exercise, but not
violent or exhausting. That which is rather passive
will be the best, such as riding in a carriage, and fre-
quent friction of the whole skin, for which sweet-scent-
ed and strong ointments may be employed with great
advantage, in order to lessen the rigidity of the skin, and
to preserve it in a state of softness. Violent bodily
shocks must in particular be avoided. These, in gene-
ral, lay a foundation for the first cause of death.

7th. A pleasant frame of mind, and agreeable em-
ployment for it, are here of uncommon utility ; but vio-
lent passions, which might derange it, and which in old
age may occasion instant death, ought to be avoided.
That serenity and contentment which are excited by
domestic felicity, by the pleasant review of a life
spent not in vain, and by a consoling prospect of the
future even on this side the grave, are the most salu-
tary. The frame of mind best fitted and most bene-
.ficial to old age, is that produced by intercourse with
-children and young people. Their innocent pastime
and youthful frolics have something which tend, as it

TREATMENT OF OLD AGE. 325

were, to renovate and revive. Hope, and extending
our views of life, are in particular noble assistants for
this purpose. New proposals, new plans and under-
takings, which, however, must be attended witn noth-
ing dangerous, or that can create uneasiness, in a
word the means of continuing life longer in idea, may
even contribute something towards the physical pro-
longation of it. We find, therefore, that old people are
impelled to this as if by internal instinct. They begin
to build houses, to lay out gardens, etc. ; and seem,
in this little self-deception, by which they imagine they
secure life, to find an uncommon degree of pleasure.

CHAPTER XIX.

Cultivation of the mental and bodily powers.

IT is only by culture that man acquires perfection.
If he is desirous of enjoying the preeminence of human
nature, his spiritual as well as his physical powers must
obtain a certain degree of expansion, refinement, and
exaltation. In a rude and uncultivated state he is not a
man : he is only a savage animal, who has certain dispo-
sitions which fit him for becoming a man ; but as long as
these dispositions are not expanded by culture, he is
raised, neither physically nor morally, above the other
classes of animals in the like situation. The essential
part of man which he possesses is his susceptibility of
perfection ; and his whole organization is so ordered
that he may either become nothing or every thing.

The influence, therefore, which culture has in bring-
ing to perfection the physical man, as well as in pro-
longing life, is highly worthy of attention. It is gen-
erally believed that all cultivation tends to weaken and
to shorten physical existence ; but this is the case only
in regard to the extreme, for hyperculture, which makes
man too delicate and refined, is as pernicious and un-
natural as the other extreme, want of cultivation, when
the faculties are not, or have been too little, expanded.
33 y both these, the duration of life is shortened. Nei-
ther the man, therefore, who by culture has become too

MENTAL AND PHYSICAL CULTIVATION. 327

tender, or who leads too sensual or too spiritual a life,
nor the rude savage, ever attains to that term of life
which man is actually capable of reaching. On the
other hand, a proper and suitable degree of mental and
bodily culture, and, in particular, a harmonic formation
of all the powers, is, as has been already shown, abso-
lutely requisite, before man can attain to that preemi-
nence over animals, in his physical state and vital dura-
tion, of which he is really susceptible.

It is well worth the trouble to examine and explain
more accurately the influence which real culture has in
prolonging life, and to establish how far it differs from
that which is false. In lengthening our existence it acts
in the following manner :

It expands the organs to perfection, and consequently
renders life richer as well as fuller of enjoyment ; and
occasions more abundant restoration. How many means
of restoration, unknown to the savage, has the man who
possesses a cultivated mind !

It renders the whole texture of the body somewhat
softer and tenderer ; consequently lessens that too great
hardness which impedes duration of life.

It secures us against those destructive and life-short-
ening causes which deprive many savages of their ex-
istence ; such as cold, heat, the influence of the weather,
hunger, poisonous and pernicious substances, etc.

By reason and moral formation, it moderates and
regulates the passionate and merely animal part within
us ; teaches us to support misfortunes, injuries, and the
like ; and, by these means, moderates the too violent
and active vital consumption, which would soon destroy
us.

328 MEANS WHICH PROLONG LIFE.

It is the foundation of social and political connections,
by which mutual aid laws and police establishments*'
become possible ; and these have a mediate effect in
prolonging life.

Lastly, it makes us acquainted with a multitude of
convenience and means for rendering life more agree-
able ; which are, indeed, less necessary in youth, but
which are of the utmost importance in old age. Nour-
ishment refined by the art of cookery, exercise made
easier by artificial helps, more perfect refreshment and
rest, are all advantages by which man in a cultivated
state can support life much longer in old age, than man
in the rude state of nature.

From this it already appears what degree and what
kind of culture are necessary in order to prolong life
those which physically, as well as morally, have for
their object the highest possible formation of our powers,
but which are always regulated by that supreme moral
law, to which every thing, to be good, suited to its end,
and really beneficial, must have a relation.

delicate sharpness of satire, in a felicity of touch which often surpasses the
felicity of Addison, in a subtilty of insight which often reaches farther than the
subtilty of Steele, the humor of Hawthorne presents traits so fine as to be
almost too excellent for popularity ; as, to every one who has attempted their
criticism, they are too refined for statement. The brilliant atoms flit, hover, and

known, in the unshaken faith that they will spring up, and bear fruit a hundred
fold. His works, to be as widely read as they deserve, should be in every dwell-
ing in the land." PORTLAND TRANSCRIPT.

a short time, many thousand copies have been sold. 1 vol. 16mo. Cloth,

" For plainness of speech, for strength of expression, and decision in stating
what the writer believes to be the truth, this lecture may be matched against any
thing that ever came from the press." CHRISTI AH- EXAMINER.

JOHN G. SAXE.

HUMOROUS AND SATIRICAL POEMS. 1 vol. 16mo. 50 cents.

" Mr. Saxe has struck upon a vein, for which few of our dealers in verse have
exhibited an aptitude. He gives us the comical phase of things, preserving always
a serene good humor. He writes with vigor, ease, and a sort of bonhomie, which
at once places him and his reader on good and friendly terms. There is a pun-
gency full of sparkle and point in his stanzas." BOSTON TRANSCRIPT.

GEORGE S. HILLARD.

THE DANGERS AND DUTIES OF THE MERCANTILE PRO-
FESSION. 1 vol. IGmo. 25 cents.

"We have twice read this admirable address, and feel that wo cannot too
warmly commend it to all our readers. It is written in a noble spirit, and in that
style of simple elegance which attests not alone the rare scholarship, but the re-
fined taste, of the author." NATIONAL ERA.

PHILIP JAMES BAILEY.

THE ANGEL WORLD, and other Poems. By the author of
" Festus." 1 vol. IGmo. 50 cents.

" The principal poem is full of beauties, and seems to us, on a hasty perusal, to
be far above ' Festus,' in point of moral eminence at least. The commencement
is worthy of the subject ; and the description of a ' Young and Shining Angel,'
who steps into the throng of bright immortals, seems to us to embody all that
is holy and beautiful in poesy.

' In his air

Sat kingly sweetness, kind and calm command,
Yet with long suffering blended ; for the soil
Of dust was on his garb and sandalled sole
Dust on the locks of fertile gold which flowed
From his fair forehead, rippling down his neck
Bedropt, denied with cold and cave-like dew.
One hand a staff of vi rent emerald held
As 'twere a sapling of the free of life ;
And one smoothed in his breast a radiant dove,
Fluttering its wings in lightnings, thousand hued,
The sole companion of his pilgrimage.
Silent he stood and gazed.'

" The shorter poems seem to us quite worthy of the author's distinguished
celebrity. Somebody said of Bailey we think it was Elliott, the Corn-Law
poet that there was matter enough in the author of ' Festus' to set up fifty
poets ; and Alfred Tennyson wrote not long ago that he could scarcely trust him-
self to say how much he admired Bailey's poems, for fear of falling into extrava-
gance. We have no doubt that the judgment of these two great authorities will
be fully indorsed by the readers of ' The Angel World ' througnout our country."

GEORGE COMBE.

THE CONSTITUTION OF MAN, considered in Relation to Ex-
ternal Objects. By George Combe. 1 vol. 12mo. 75 cents.
" Of the merits of this work it is almost needless to speak, as its extensive
adoption, as a general reading*book in families and class book in schools, has
made its reputation every where familiar. There are few books extant, the uni-
versal introduction ot which would be productive of more benefit." NAT. INTEL.

ALFRED TENNYSON.

COMPLETE POETICAL WORKS. Illustrated -with a fine portrait
of the author. 2 vols. IGmo. $1.50. Cloth, $1.75 ; gilt, $2.50.

" There are few living poets who can be compared with Tennyson in those
peculiar, distinctive qualities which raij;e the true poet to that quick apprehension
of spiritual beauty which furnishes him with perpetual inspiration, and to the
glad world an overflowing song." EDINBURGH REVIEW.

" Of the living poets of England we include not the few choice spirits of
Scotland Tennyson at this time occupies the highest rank, and he is destined
to a wide and high regard." DR. GRISWOLD.

THE PRINCESS : A Medley. 1 vol. 16mo. 50 cents. Gilt, $1.

" If we were to express the feeling of satisfaction with which we have just read
every word of this beautiful, charming, and profound little book, we should be
thought extravagant. Nor does it stand in need of any enthusiastic commenda-
tion to secure for it a very large circle of readers; for, of all living poets, hardly
any has a wider or more desirable reputation in this country than Tennyson. The
mere announcement of a new poem from his pen will send thousands on an im-
mediate pilgrimage to their respective bookstores." N. Y. TRIBUNE.

IN MEMORIAM. 1 vol. 16mo. Cloth, 75 cents.

" The most exquisite creation by any man of genius during the last forty years."
EDINBURGH REVIEW.

WILLIAM MOTHERWELL.

THE POETICAL WORKS. With a Memoir by James M'Conechy,
Esq. A new edition, enlarged. 1 vol. IGmo. 75 cents. Cloth, 88 cents j
gilt, $125.

"Motherwell was a poet of the right cast a man of fire and inspiration.
When we read his verses we feel that the writer is not mocking us with an affec-
tation of what he describes, but that he has surrendered himself, heart and soul,
to the passion that carries us along with him." LITERARY WORLD.

POSTHUMOUS POEMS. 1 vol. 16mo. 50 cents.

MINSTRELSY, ANCIENT AND MODERN. Edited by Mother-
well. With an Historical Introduction and Notes. 2 vols. IGino. $1.50.
Cloth, $1.75; gilt, $2.50.

" In fact, it is a book which takes after the heart of almost any body who has
one ; and with its rich Scotch brogue, and its high-strung Scotch feeling, it must
be a hard heart that will not bo touched now and then with it." CHROMOTYPE.

" Most of the ballads he has selected are beautiful specimens of that natural
poetry which springs directly from the heart and imagination in words and images
fresh and bright from Nature's own mint. The interest o f the reader is enhanced
by feeling that he is reading poems which were sung, centuries ago, in the palace
halls, and by the cottage hearths of a whole nation, and which formed the litera-
ture of thousands on thousands of minds who had no other. Every thing in them

betokens youth of feeling. The minstrels seem to have looked upon nature
as if it had just come from the Creator's hand, and as if they were the first to
exercise upon it the plastic powers of imagination and passion." COURIER.

RICHARD MONCKTON MILNES.

POEMS OF MANY YEARS. 1 vol. 16mo. 75 cents ; cloth, 88

cents ; gilt, $ 1.25.

" The author, who is or was a member of Parliament, has, for the last ten
years, divided with Tennyson the admiration and affection of 'Young Eng-
land.' His style is eminently pure, and something in the Wordsworthian strain.
' The Lay of the Humble' is one of the most touching things in the language.
We never saw a thoughtful child that could read it without shedding tears ; and
many a childlike man has wept over its simple pathos and beauty. Milnes is too
sincere and sensitive not to please the million. His poems are full of beauties."

HORACE AND JAMES SMITH.

REJECTED ADDRESSES; or the New Theatrum Poetarum.

From the last London edition, carefully revised, with an original preface

and notes by the authors. 1 vol. 16mo. 50 cents.

" In selecting one of the raciest and wittiest works of the age for republication,
Ticknor & Co. have certainly evinced as much judgment as the whole appear-
ance of the work betrays good taste and the perfection of the art of printing."
TIMES.

WARRENIANA. 1 vol. 16mo. 63 cents.

BARRY CORNWALL.

ENGLISH SONGS, and other Small Poems. A new and enlarged
edition. 1 vol. 16mo. 88 cents.

" Barry Cornwall (B. W. Proctor) is a name that should be on every book
shelf which at all pretends to contain the works of modern English poets. In
his own domain he is almost unexcelled." TIMES.

"The songs of Barry Cornwall are too widely known, too justly prized, to be
reviewed casually now. In contemplating them, criticism gives place to admira-
tion, whose speech is silence. We had intended only to introduce a few selec-
tions from this glorious volume selections difficult to make, because so many
of these songs are already household words to us all. To quote ' King Death,'
The Sea,' ' The Hunter's Song,' &c., would be superfluous." TRIBUNE.

EPES SARGENT.

SONGS OF THE SEA, with other Poems. 1 vol. 16mo. 50

cents; gilt, 75 cents.

" Mr. Sargent has an admirable faculty of description ; his pictures are true
and living, and never exaggerated. The most striking feature of his verse is ac-
tion ; every thing moves with him. His diction, too, is uncommonly good. His
< Life on the Ocean Wave ' is perfect ; when we read it, we feel the fresh breeze
rushing against our cheeks, and the blood starting in our veins, as the ship tri-
umphs over the waves." N. Y. TRIBUNE.

FANNY FORESTER.

ALDERBROOK. A Collection of Fanny Forester's Village
Sketches, Poems, &c. With a fine mezzotinto portrait of the author, en-

$2.50; extra gilt, $3.00. The same in 1 vol., $1.62: gilt, $2.25: extra
gilt, $2.75.

" This is one of those charming books which well deserve a place in every
family library, and which has already won a place in thousands of hearts. The
sketches comprised in these beautiful volumes are so full of grace and tenderness,
so pure in their style, and so elevated in their tone, that none can read them with-
out delight and profit. We hazard little in saying that the touching story of
'Grace Linden,' which properly leads the collection, is scarcely surpassed in
beauty by any thing in the works of Maria Edgeworth or Mary Russell Mitford.
There are a great many other sketches in the volumes that deserve special praise,
but we will not deal in particulars when all are so admirable." So. LIT

triumph. With me desire this, O reader, and farewell! " LEIBNITZ. 2
vols. 16mo. $ 2.50.

" We have Mr. Sumner's printed discourses before us, and can testify from
personal knowledge to their singular merits. They are pregnant with thoughts
of profound and universal interest. They are not productions to be laid aside
with the occasion that called them forth, but to be preserved for our future in-
struction and delight. They derive this quality, in a great measure, from those
characteristics of the author's mind his earnestness, the union of moral fear-
lessness and intellectual caution in the statement of his opinions, and his rever-
ence for original principles in comparison with popular custom or fashionable
belief:" NEW YORK TRIBUNE.
